Maintain healthy aquarium water with the Fritz Aquatics Master Test Kit, a convenient liquid aquarium water testing kit designed to help monitor essential water parameters in freshwater and saltwater aquariums. This all-in-one aquarium test kit includes four essential tests for pH, ammonia, nitrite, and nitrate, making it an excellent choice for new aquarium setups, routine water quality checks, and established fish tanks.

Whether you're cycling a new aquarium, maintaining a freshwater community tank, or caring for a saltwater aquarium, the Fritz Master Test Kit helps you identify potential water quality problems before they become more serious. With liquid reagents, test tubes, clear instructions, and easy-to-read color charts, this aquarium water test kit makes regular water testing simple and convenient.

Four Essential Aquarium Water Tests in One Kit

The Fritz Master Test Kit combines four individual liquid test kits to help you monitor the most important water parameters for aquarium health.

• pH Test: Measures the acidity or alkalinity of aquarium water to help you maintain conditions suitable for your fish and other aquatic life.

• Ammonia Test: Detects ammonia, a potentially toxic compound that can accumulate in new aquariums, overstocked tanks, or systems with disrupted biological filtration.

• Nitrite Test: Monitors nitrite levels during aquarium cycling and routine maintenance to help identify problems with biological filtration.

• Nitrate Test: Measures nitrate accumulation, helping you determine when water changes and other maintenance may be needed.

Together, these four tests provide valuable information about aquarium water quality and the progress of the biological filtration cycle.

Ideal for New Aquariums and Aquarium Cycling

Establishing a new aquarium requires careful monitoring of ammonia, nitrite, and nitrate as beneficial bacteria develop in the biological filter. The Fritz Master Test Kit helps aquarium owners follow these changes and recognize when water parameters need attention.

It is also useful for established aquariums, where regular testing can reveal changes caused by excess fish waste, overfeeding, insufficient maintenance, or filtration problems.

Suitable for Freshwater and Saltwater Aquariums

The Fritz Master Test Kit is designed for use with both freshwater and saltwater aquariums. Its wide-range pH test, ammonia test, nitrite test, and nitrate test help fishkeepers monitor water conditions across a variety of aquarium environments.

Use it for freshwater community tanks, planted aquariums, tropical fish tanks, marine aquariums, and other compatible aquarium setups.

Easy-to-Use Liquid Aquarium Test Kit

Testing your aquarium water is straightforward. Collect a water sample in the included test tube, add the specified liquid reagents according to each test's instructions, allow the required color-development time, and compare the resulting color with the appropriate chart.

The kit includes the reagents and testing accessories needed to perform the four included tests, helping you keep your aquarium maintenance routine organized.

Keep your aquarium water safe for fish and other aquatic life with Fritz Complete Water Conditioner, a concentrated, full-spectrum aquarium water conditioner designed to neutralize chlorine and chloramine while detoxifying ammonia, nitrite, and nitrate. This powerful all-in-one water treatment helps make tap water suitable for aquarium use and supports water quality management during aquarium setup, routine water changes, and unexpected water quality problems.

Suitable for freshwater, saltwater, reef, and planted aquariums, Fritz Complete provides convenient, one-step water conditioning for both beginner and experienced aquarists. Its concentrated formula treats large volumes of water with a small amount of product, making it a practical addition to any aquarium maintenance routine.

Removes Chlorine and Chloramine from Tap Water

Municipal tap water often contains chlorine or chloramine to disinfect drinking water, but these chemicals can harm fish and beneficial aquarium bacteria. Fritz Complete helps neutralize chlorine and chloramine, allowing you to prepare replacement water before adding it to your aquarium.

For best results, add Fritz Complete to tap water before introducing the treated water into your fish tank.

Detoxifies Ammonia, Nitrite and Nitrate

Fritz Complete is more than a standard aquarium dechlorinator. Its full-spectrum formula also detoxifies ammonia, nitrite, and nitrate, helping you manage potentially harmful nitrogen compounds in aquarium water.

This makes it especially useful during new aquarium cycling, routine tank maintenance, and situations where water testing reveals elevated nitrogen compounds. Continue testing your aquarium water and performing appropriate water changes, as water conditioning does not replace proper filtration and aquarium maintenance.

Ideal for Freshwater, Saltwater and Reef Aquariums

The versatile Fritz Complete formula is designed for use in a wide range of aquarium environments, including:

• Freshwater fish tanks

• Saltwater aquariums

• Marine and reef aquariums

• Planted aquariums

• New aquarium setups

• Routine aquarium water changes

• Aquarium water quality management

Fritz Complete does not affect aquarium pH when used as directed and is designed not to over-activate protein skimmers.

Concentrated Formula for Easy Aquarium Water Treatment

The recommended dosage is 5 mL (1 teaspoon) per 50 US gallons (189 liters) of water. This concentrated formula makes it easy to treat large quantities of tap water without adding excessive amounts of conditioner.

When treating aquarium water for ammonia, nitrite, or nitrate, calculate the dose based on the total aquarium volume rather than only the amount of replacement water.

For extremely high chloramine or nitrite levels, the manufacturer allows repeat or increased dosing under specified conditions. Follow the official instructions carefully, avoid overdosing, and ensure adequate water circulation and aeration.

Easy to Use for Routine Aquarium Maintenance

Whether you're filling a new aquarium, performing a partial water change, or responding to elevated ammonia levels, Fritz Complete offers a convenient way to condition aquarium water.

Simply measure the appropriate amount, add it to the replacement water before adding that water to the aquarium, and follow the manufacturer's directions for any treatment of existing aquarium water.

Important testing note: Fritz Complete can interfere with Nessler-type ammonia tests and Winkler-type oxygen tests. The manufacturer recommends salicylate-based ammonia test kits for compatible ammonia testing.

• Full-spectrum aquarium water conditioner

• Neutralizes chlorine and chloramine

• Detoxifies ammonia, nitrite, and nitrate

• Suitable for freshwater and saltwater aquariums

• Safe for reef and planted aquariums when used as directed

Help protect your fish from common external parasites with Fritz FixIck, a specialized aquarium ich treatment designed to treat Ich (Ick) and other protozoan parasites in freshwater and saltwater aquariums. This fast-acting fish medication targets common external parasitic infections, including Chilodonella, Trichodina, and Tetrahymena, helping aquarium owners manage fish health problems with a convenient treatment regimen.

Unlike many traditional ich medications, Fritz FixIck is formulated without formaldehyde or malachite green. Its formula includes gentian violet and is designed to provide effective parasite treatment while offering an alternative to some harsher conventional treatments. The distinctive purple color is characteristic of the product.

Whether you're treating an affected freshwater aquarium or managing parasitic infections in a saltwater fish system, Fritz FixIck provides a targeted treatment option for common external fish parasites.

Effective Treatment for Ich and External Parasites

Ich, also known as Ick or white spot disease, is a common parasitic infection that affects aquarium fish. Fritz FixIck is formulated to treat Ich and several other external protozoan parasites, including:

• Ich (Ick) and white spot disease

• Chilodonella

• Trichodina

• Tetrahymena

The manufacturer also reports additional antibacterial and antifungal properties that may help address certain secondary infection concerns.

Formaldehyde-Free and Malachite Green-Free Formula

Fritz FixIck offers an alternative to traditional ich treatments by excluding formaldehyde and malachite green from its formula. Gentian violet is one of its active ingredients and gives the medication its recognizable purple appearance.

This formulation is designed to provide effective treatment without relying on those two commonly used chemicals. Always follow the product label and observe fish closely throughout treatment.

Suitable for Freshwater and Saltwater Fish

Fritz FixIck is designed for use in freshwater and saltwater aquariums containing compatible fish. It can be used as part of a fish health management routine when external protozoan parasites are identified.

For best results, Fritz Aquatics recommends treating affected fish in a separate quarantine tank when possible. This can help simplify treatment and reduce unnecessary exposure of other aquarium inhabitants.

Important: Fritz FixIck is not recommended for systems containing invertebrates or coral. Shrimp, snails, clams, crabs, other crustaceans, mollusks, and corals must be removed before treatment.

Six-Day Aquarium Ich Treatment

Fritz FixIck uses a straightforward treatment schedule. Follow the current product label and manufacturer instructions carefully.

• Day 1: Add 5 mL per 10 US gallons of aquarium water.

• Day 2: Repeat the same dose.

• Day 3: Perform a 25–30% water change.

• Day 4: Repeat the recommended dose.

• Day 5: Repeat the recommended dose.

• Day 6: Perform a 25–30% water change.

Shake the bottle well before each dose. The manufacturer recommends raising the water temperature to 82–85°F before treatment, but only do so if the fish species and aquarium inhabitants can safely tolerate that temperature. Maintain adequate aeration and monitor fish for signs of distress.

During treatment, remove activated carbon and ion-exchange resins, and discontinue protein skimmers and UV sterilizers as directed. Avoid water changes during the course when possible; if a water change is necessary, follow the manufacturer's instructions for treating replacement water.

Available Sizes

Choose the bottle size that suits your aquarium treatment needs:

• 8 oz: Treats up to 480 gallons over a complete treatment course.

• 16 oz: Treats up to 946 gallons over a complete treatment course.

  The amount treated reflects the manufacturer's stated treatment capacity and accounts for the repeated doses in the treatment schedule.

Help treat bacterial infections in aquarium fish with Fritz Maracyn Two, a broad-spectrum antibiotic formulated for freshwater and saltwater aquariums. Containing minocycline as its active ingredient, this fish medication is primarily effective against gram-negative bacteria associated with common aquarium fish illnesses, including fin and tail rot, popeye, dropsy, septicemia, and certain internal bacterial infections.

Unlike treatments that work mainly by dissolving into the aquarium water, Fritz Maracyn Two is absorbed through the fish’s skin, allowing the medication to reach therapeutic levels in the fish’s body during treatment. This makes it a useful option when addressing susceptible bacterial infections that may affect more than the outer surface of the fish.

Whether you're caring for freshwater community fish or marine aquarium species, Fritz Maracyn Two provides a targeted antibiotic treatment option for managing certain bacterial diseases. For the best results, identify the suspected infection when possible, follow the manufacturer’s dosing instructions, and monitor water quality throughout treatment.

Effective Treatment for Bacterial Fish Infections

Bacterial infections can affect aquarium fish in different ways, from visible fin damage to more serious systemic illness. Fritz Maracyn Two is primarily formulated to target gram-negative pathogenic bacteria and may help treat conditions such as:

• Fin and tail rot

• Popeye (swollen or protruding eyes associated with infection)

• Dropsy-related bacterial infections

• Septicemia

• Certain internal bacterial infections

• Secondary bacterial infections associated with wounds or parasite damage

Possible signs of illness include frayed or deteriorating fins, unusual lethargy, reduced appetite, clamped fins, or changes in normal swimming behavior. These symptoms can have several causes, so they should not automatically be assumed to indicate a bacterial infection. Consult an aquatic veterinarian or qualified fish-health professional if the diagnosis is uncertain or symptoms persist.

Minocycline-Based Antibiotic Formula

Fritz Maracyn Two contains minocycline, an antibiotic that is primarily effective against gram-negative bacteria. The medication is absorbed through the fish’s skin, helping deliver the active ingredient internally to combat susceptible infections.

The formula may also be effective against some gram-positive bacteria and fungal infections, according to the manufacturer, but it should not be considered a universal treatment for every disease. Selecting the appropriate medication depends on the organism responsible for the illness.

Use antibiotics responsibly and complete the prescribed course according to the product label, even if visible symptoms begin to improve before treatment ends.

Suitable for Freshwater and Saltwater Aquariums

Fritz Maracyn Two is designed for use in both freshwater and saltwater aquariums. It can be used to treat compatible ornamental fish when a susceptible bacterial infection is suspected.

For best results, Fritz Aquatics recommends using Maracyn Two in a separate quarantine or hospital tank when practical. This can make it easier to monitor the affected fish, manage treatment, and observe water conditions without unnecessarily medicating the display aquarium.

The manufacturer states that Maracyn Two is safe for use with invertebrates. However, responses can vary by species and aquarium conditions, so observe all tank inhabitants closely and follow the product label.

Five-Day Aquarium Antibiotic Treatment

Fritz Maracyn Two uses a five-day dosing schedule followed by a water change on day six. Follow the current package instructions and calculate the dose based on the actual volume of aquarium water.

• Day 1: Add the contents of two packets per 10 US gallons of aquarium water.

• Day 2: Add one packet per 10 US gallons.

• Day 3: Add one packet per 10 US gallons.

• Day 4: Add one packet per 10 US gallons.

• Day 5: Add one packet per 10 US gallons.

• Day 6: Perform a 25% water change.

Complete the full five-day treatment even if symptoms improve or disappear sooner. If symptoms improve but have not completely cleared, the manufacturer permits repeating the five-day course once. If there is no improvement, reassess the diagnosis and consult a fish-health professional rather than repeatedly using an ineffective medication.

Important Treatment Instructions

• Remove activated carbon during treatment, as it can remove medication from the water.

• Maintain adequate water circulation and aeration.

• Do not perform routine water changes during the five-day dosing period unless water quality or fish distress makes intervention necessary.

• Maracyn Two may inhibit beneficial nitrifying bacteria, which can contribute to elevated ammonia or nitrite. Test water regularly and take appropriate steps if levels rise.

• Cloudiness may develop during treatment and should clear on its own, according to the manufacturer.

• Protein skimmers may produce excessive foam. Discontinue skimmer use during treatment if foaming becomes a concern.

• The manufacturer states that UV sterilizers can remain in use during treatment.

• If fish show signs of distress following an accidental overdose, perform a large water change as directed by the manufacturer.

Always follow the instructions supplied with your specific product and seek expert advice if the fish's condition worsens.

Help manage common bacterial infections in aquarium fish with Fritz Maracyn, a broad-spectrum antibiotic formulated for freshwater and saltwater aquariums. Containing erythromycin as its active ingredient, this medication is primarily effective against gram-positive bacteria associated with ornamental fish diseases. Fritz Maracyn is commonly used to treat conditions such as bacterial gill disease, popeye, mouth fungus, open lesions, hemorrhagic septicemia, and slime disease.

Unlike medications designed specifically for external parasites, Fritz Maracyn targets susceptible bacterial pathogens that can affect fish health and appearance. Its powder formula dissolves gradually in aquarium water, making it convenient to administer as part of a structured treatment routine.

Whether you're caring for a freshwater community aquarium or a saltwater fish system, Fritz Maracyn provides a targeted treatment option for certain bacterial infections. For best results, follow the manufacturer’s dosing instructions and seek expert guidance if the cause of the fish’s symptoms is unclear.

Effective Treatment for Common Bacterial Fish Infections

Bacterial diseases can affect fish in several ways, including irritation of the gills, damaged tissue, swollen eyes, and open sores. Fritz Maracyn is formulated to help treat susceptible bacterial infections associated with conditions such as:

• Bacterial gill disease

• Popeye (swollen or protruding eyes)

• Mouth fungus, which may resemble a fungal growth but can be bacterial in origin

• Open lesions and sores

• Hemorrhagic septicemia

• Slime disease

Possible signs of bacterial illness include clamped fins, rapid or labored breathing, patchy coloration, unusual swimming behavior, hiding, or swollen eyes. These symptoms can have different causes, so an accurate diagnosis is important when selecting a treatment.

Erythromycin-Based Antibiotic Formula

Fritz Maracyn contains erythromycin, an antibiotic that is primarily effective against gram-positive pathogenic bacteria. The medication gradually dissolves in aquarium water, allowing it to be administered throughout the treatment period.

This makes Maracyn a useful option for certain bacterial infections affecting ornamental fish. It is not a universal treatment for all fish diseases, however, and it should not be confused with Fritz Maracyn Two, which contains minocycline and primarily targets gram-negative bacteria.

For suspected bacterial infections, choose a medication appropriate to the likely cause of illness and complete the recommended course according to the product label.

Suitable for Freshwater and Saltwater Aquariums

Fritz Maracyn is designed for use in both freshwater and saltwater aquariums. It can be used to treat compatible ornamental fish affected by susceptible bacterial infections.

For best results, Fritz Aquatics recommends using Maracyn in a separate quarantine or hospital tank when practical. This makes it easier to observe affected fish, manage treatment, and monitor their condition.

The manufacturer states that Maracyn is safe for use with invertebrates. Some sensitive aquatic plants may develop yellowing during treatment, so monitor plants and other aquarium inhabitants throughout the course.

Help protect aquarium fish from common parasitic infections with Fritz MetroCleanse, a metronidazole-based treatment designed for freshwater and saltwater aquariums. Formulated to address certain protozoan parasites and bacterial infections, MetroCleanse is used to treat conditions associated with Ich, Hexamita, and Oodinium, commonly known as velvet. It is also effective against certain internal and external parasitic and bacterial infections.

With two application methods available, Fritz MetroCleanse can be added directly to aquarium water or mixed into fish food. This flexibility allows aquarists to select a treatment approach suited to their aquarium and the condition being addressed. When medicated food is used, the treatment can also be administered in systems containing invertebrates, following the manufacturer's directions.

Whether you're managing a freshwater aquarium or a marine fish system, Fritz MetroCleanse provides a targeted treatment option for certain parasitic and bacterial health concerns. For best results, follow the product instructions carefully and monitor fish behavior and water quality throughout treatment.

Effective Treatment for Common Fish Parasites

Parasitic infections can affect fish externally, internally, or both, depending on the organism involved. Fritz MetroCleanse contains metronidazole and is formulated to help treat several common protozoan infections, including:

• Ich (Ick): A parasitic disease commonly associated with small white spots and rubbing or scratching against aquarium surfaces.

• Hexamita: A protozoan parasite associated with certain internal infections in fish.

• Oodinium (velvet): A parasitic disease that may cause fine yellowish or gold-colored spots, color loss, and irritation.

• Certain internal parasitic infections: MetroCleanse can be used against susceptible internal parasites according to the manufacturer's directions.

• Certain bacterial infections: The manufacturer also identifies activity against some bacterial infections.

Symptoms such as rapid breathing, excess mucus, appetite loss, unusual swimming, or repeated scratching can have several causes. Correctly identifying the suspected disease helps determine whether MetroCleanse is an appropriate treatment.

Metronidazole-Based Formula

Fritz MetroCleanse contains metronidazole, an active ingredient used to target susceptible protozoan organisms. It is formulated for aquarium use and comes in a fast-dissolving powder that can be administered through the aquarium water or incorporated into food.

The water-treatment method exposes fish to the medication through the aquarium environment, while medicated food delivers it through feeding. The most suitable approach depends on the suspected infection, whether the fish are eating, and the other inhabitants of the aquarium.

MetroCleanse is not a universal remedy for every parasite or bacterial disease. Use it for conditions listed by the manufacturer and consult an aquatic veterinarian or qualified fish-health professional if symptoms persist or the diagnosis is uncertain.

Suitable for Freshwater and Saltwater Aquariums

Fritz MetroCleanse is designed for use in both freshwater and saltwater fish systems. It can be used as part of a treatment plan for compatible ornamental fish affected by susceptible parasitic or bacterial infections.

For best results, the manufacturer recommends treating fish in a separate hospital or quarantine aquarium when practical. This makes it easier to observe the affected fish, manage medication, and monitor water parameters.

Important: If dosing MetroCleanse directly into aquarium water, remove all invertebrates before treatment. The manufacturer permits use in systems containing invertebrates when the medication is administered through medicated food according to the label directions. This includes aquariums containing corals, shrimp, snails, clams, and other crustaceans or mollusks.

Two Convenient Treatment Methods

Fritz MetroCleanse offers two ways to administer the medication. Always use the current package instructions and measure the aquarium's actual water volume as accurately as possible.

Method 1: Direct Aquarium Water Treatment

For broadcast treatment, the manufacturer recommends the following schedule:

• Dosage: Add one packet per 20 US gallons of aquarium water.

• Frequency: Repeat every 48 hours until symptoms disappear.

• Maximum course: Do not exceed ten treatments.

• Before dosing: Remove all invertebrates from the aquarium.

• During treatment: Maintain adequate water flow and aeration, and monitor water quality.

For best results, use a quarantine or hospital tank when practical. Remove activated carbon and ion-exchange resins during treatment, and discontinue UV sterilizers and protein skimmers as directed by the manufacturer. Avoid water changes during treatment when possible, provided aquarium conditions remain safe.

Method 2: Medicated Fish Food

For aquarists who prefer to administer medication through feeding, MetroCleanse can be mixed into the fish's normal food.

• Mix one packet per tablespoon of normal fish food.

• Add a small amount of water if the food is dry to help incorporate the medication.

• Feed the medicated mixture daily until symptoms disappear, for up to three weeks.

• Refrigerate or freeze leftover medicated food between feedings.

• Follow the label directions and observe whether the fish are eating normally.

The medicated-food method is the manufacturer's recommended option when treating fish in systems containing invertebrates. No filtration adjustment is required for this method, according to the manufacturer.

Important Treatment Instructions

• Maintain adequate aeration and water circulation throughout treatment.

• Remove activated carbon and ion-exchange resins when using the water-treatment method.

• Turn off UV sterilizers during water treatment.

• In marine aquariums, discontinue protein skimmers during treatment and resume their use after treatment is complete.

• Avoid unnecessary water changes while treating if aquarium parameters remain within safe ranges.

• Monitor ammonia and nitrite, particularly in systems where biological filtration may be affected.

• When treatment is complete and symptoms have resolved, replace chemical filtration and resume normal equipment operation and feeding.

• If an overdose occurs, the manufacturer recommends removing the medication with carbon-based media or a suitable product such as Fritz MaxOut Pro.

Always follow the current package label. If fish show signs of distress or water quality deteriorates, prioritize fish safety and take appropriate corrective action.

Help protect aquarium fish from internal parasitic worms with Fritz Expel-P, a targeted deworming treatment designed for freshwater and saltwater aquariums. Formulated with levamisole hydrochloride, this anti-parasitic medication is especially effective against nematodes and other susceptible roundworms that can affect fish health, appetite, and body condition.

Fritz Expel-P is designed to treat parasites such as roundworms, nodular worms, and hookworms. These infections may cause visible worms protruding from a fish's anus, weight loss, abdominal bloating, reduced appetite, or unusual breathing. By targeting susceptible parasitic worms, Expel-P helps aquarium owners manage internal parasite problems with a convenient packet-based treatment.

In addition to aquarium fish treatment, Fritz Expel-P can also be used as a coral dip to help remove certain flatworms and pest nudibranchs. Its versatile formula makes it a useful option for both freshwater and marine aquarium care when applied according to the manufacturer's directions.

Effective Treatment for Internal Fish Worms

Internal parasites can interfere with digestion, nutrient absorption, and overall fish condition. Fritz Expel-P contains levamisole hydrochloride, an anthelmintic ingredient used to treat susceptible parasitic worms.

The product is formulated to target:

• Nematodes: Parasitic roundworms that can live within fish and affect their health.

• Roundworms: Internal worms that may contribute to wasting, poor appetite, and reduced body condition.

• Nodular worms: Parasites associated with nodules or abnormal tissue growth.

• Hookworms: Susceptible parasitic worms that can affect fish health.

Possible signs of infection include a thinning body despite eating, abdominal swelling, reduced interest in food, rapid breathing, or worms visibly extending from the vent. These symptoms can have multiple causes, so accurate identification is important when selecting a treatment.

Important: Fritz Expel-P does not treat tapeworms or flukes. For those parasites, consider an appropriate alternative such as Fritz ParaCleanse or another product specifically labeled for the identified organism.

Levamisole-Based Deworming Formula

Fritz Expel-P contains levamisole hydrochloride, an active ingredient used to control susceptible internal parasitic worms. Each packet contains 113 mg of levamisole hydrochloride, providing a convenient way to measure treatment doses.

The formula is designed for use in freshwater and saltwater aquariums and can help manage worm infections without harming the biological filter when used as directed. The manufacturer also identifies an immunostimulant benefit, making Expel-P a useful addition to an aquarium fish-health routine.

Expel-P is intended for specific parasitic worms rather than every type of fish parasite. It should not be confused with treatments designed for flukes, tapeworms, protozoan parasites, or bacterial infections.

Suitable for Freshwater and Saltwater Aquariums

Fritz Expel-P is formulated for use in both freshwater and saltwater aquariums. It can be used to treat compatible ornamental fish affected by susceptible internal worms.

For best results, Fritz recommends treating fish in a separate quarantine or hospital aquarium when practical. This makes it easier to monitor affected fish, observe expelled parasites, and manage treatment.

The manufacturer states that Expel-P is safe for plants, invertebrates, and the biological filter when used as directed. Some snail species may be temporarily affected but are expected to recover.

Aquarium Worm Treatment Instructions

Fritz Expel-P uses a simple dosing schedule with a follow-up treatment to help address reinfection from parasites that remain after the initial dose.

• Initial treatment: Add one packet per 10 US gallons of aquarium water.

• After 24 hours: Perform a 25% water change and carefully remove expelled worms and parasites from the aquarium.

• One week later: Repeat the treatment to help prevent reinfection.

• Additional treatments: Repeat weekly as necessary, following the product label.

For aquariums smaller than 10 gallons, accurate dosing is important. Fritz provides instructions for preparing a diluted solution so that smaller amounts can be measured more reliably. Refer to the manufacturer's small-tank dosing guide before treating smaller systems.

Important Treatment Instructions

• Remove activated carbon and other chemical filtration media during treatment.

• Turn off UV sterilizers while treating.

• In marine aquariums, discontinue protein skimmers during treatment.

• Keep aquarium lights off during the first 24 hours because the active ingredient is light-sensitive.

• Maintain adequate water movement and aeration.

• Avoid unnecessary water changes during the initial treatment period, except for the recommended 25% change after 24 hours.

• Monitor fish closely and observe for expelled worms or signs of distress.

• If ammonia or nitrite becomes a concern, use an appropriate aquarium water conditioner according to its label.

Always follow the current package instructions and seek advice from a qualified fish-health professional if symptoms persist.

Coral Dip for Flatworms and Pest Nudibranchs

In addition to treating aquarium fish, Fritz Expel-P can be used as a dip for certain coral pests, including flatworms and pest nudibranchs.

• Dip concentration: Use three packets per two US gallons of saltwater.

• Treatment time: Place affected corals in the dip for up to 30 minutes.

• Water movement: Maintain adequate flow during the dip to help dislodge worms.

• After treatment: Return the coral to the display or quarantine aquarium once worms stop falling off, following the manufacturer's instructions.

Expel-P does not affect parasite eggs. Manually remove eggs when possible or repeat the dip after hatching. The manufacturer permits repeating coral dips once per week, up to three times.

Use a separate container for the dip, and never pour used dip water directly into the display aquarium.
