Important: The stated flow rates are manufacturer-rated siphon capacities, not electric pump outputs. Actual drainage speed depends on the height difference between the aquarium and outlet, tubing configuration, flow adjustment, and siphon conditions.
Gravel substrate can trap waste between individual particles.
Over time, fish waste, uneaten food, decaying plant material, and other organic debris may accumulate beneath the visible substrate surface.
The Hygger HG013 features a dedicated gravel cleaning tube that helps remove this debris during aquarium water changes.
Position the gravel cleaning tube over the substrate.
As water moves through the siphon, loose debris is drawn upward.
Heavier gravel particles can fall back into the aquarium while lighter waste is carried away with the water.
Regular gravel cleaning helps:
Remove accumulated fish waste
Collect uneaten food
Reduce loose organic debris
Clean substrate surfaces
Improve aquarium appearance
Support routine water quality maintenance
Reduce debris buildup in low-flow areas
The flow-control valve allows users to reduce suction when necessary.
This is especially helpful when working with smaller gravel or cleaning near aquatic plants.
The Hygger HG013 can also be used for cleaning sand substrates.
Sand requires a gentler cleaning technique than coarse aquarium gravel because individual sand particles are lighter and can be drawn into the siphon more easily.
Position the intake slightly above the sand surface.
Allow the siphon to collect loose debris without pulling excessive sand into the tube.
The HG013 can help remove:
Fish waste
Uneaten food
Loose plant debris
Detritus
Other particles resting on the sand
Use the flow-control valve to reduce the drainage rate when cleaning fine sand.
Avoid inserting the gravel tube deeply into delicate or nutrient-rich planted aquarium substrates.
The Hygger HG013 includes a duckbill-style debris suction attachment.
Its narrow opening is designed to help collect waste from areas that may be difficult to reach with a larger gravel cleaning tube.
The duckbill attachment is useful for cleaning:
Aquarium corners
Areas behind decorations
Spaces around driftwood
Bare-bottom aquarium surfaces
Areas beside rocks
Low-flow debris collection points
Narrow gaps between decorations
The narrow attachment helps direct suction toward specific areas.
This makes it useful when you want to remove a small amount of debris without disturbing a large section of the substrate.
The duckbill attachment is particularly useful for removing visible waste between regular full aquarium cleaning sessions.
The HG013 features interchangeable extension tubes that allow users to adjust the working length of the cleaning assembly.
The HG013-S can be configured to approximately 22–32 inches, depending on the selected attachments.

The Hygger HG013 includes an outlet hose measuring approximately:
78 inches / 6.5 feet / 198 cm
The hose provides flexibility when directing aquarium water into a suitable collection container.
The hose allows users to position a bucket below the aquarium while maintaining a suitable drainage connection.
The outlet hose is designed for routine aquarium water-changing applications.
The included hose fixture clamp helps prevent the outlet hose from slipping out of the collection bucket.
The HG013 uses gravity-driven siphoning.
For proper operation, the water outlet must be positioned below the aquarium water inlet.
The Large model's manual specifies a minimum vertical drop of approximately 19.7 inches / 50 cm between the inlet and outlet.
Without sufficient height difference, the siphon may not operate correctly.
The HG013 includes a manual flow-control valve that allows aquarium owners to regulate the water drainage rate.
Different aquarium cleaning tasks require different levels of suction.
For example:
Gravel cleaning may benefit from stronger water movement.
Fine sand cleaning requires gentler suction.
Small aquariums benefit from slower drainage.
Cleaning near shrimp or small fish requires extra caution.
Adjust the valve to reduce or increase water flow while cleaning.
This helps users maintain better control over the amount of water removed.
Slower flow can be useful when cleaning smaller aquariums where water levels may drop quickly.
Always monitor the aquarium water level during siphoning.
The Hygger HG013 includes a filter screen designed to reduce the risk of small fish and gravel being drawn into the siphon.
Helps block larger gravel particles
Reduces accidental intake of small fish
Helps prevent larger debris from entering the tubing
Supports more controlled aquarium cleaning
The filter screen does not eliminate the risk of accidental suction.
Always keep the intake away from delicate fish, shrimp, fry, and other small aquatic animals.
Reduce the siphon flow when cleaning around sensitive livestock.
The HG013 is designed for a variety of aquarium systems.
The HG013-S provides a practical option for aquariums where a compact cleaning tool and moderate siphon flow are preferred.
The HG013-L offers a longer reach and increased rated flow for deeper tanks and larger water-changing tasks.
The tool can help remove loose waste from substrate surfaces and spaces around aquarium plants.
