✔ Three functions in one unit: Filter aquarium water, add oxygen, and collect fish waste with one unit. Its three-in-one design combines these tasks in a single setup inside the tank.

✔ Waste collected in one compartment: Fish waste and impurities are drawn into the middle compartment while clean water returns to the tank. When the compartment fills, it can be emptied, disinfected, and rinsed before being put back.

✔ Supports the nitrogen cycle: A biological filter ball at the bottom supports nitrifying bacteria that contribute to the aquarium’s nitrogen cycle. The unit can reduce the need for frequent water changes and gravel washing and helps limit odors and contamination. An air pump is required but not included.
