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.
