Features: 1. Fish Waste Suction Collector: Fully automatic, continuous filtration system that collects fish waste. Functions as a filter, oxygenation unit, and waste collector to help maintain aquarium cleanliness. 2. How it works: Operates on a pneumatic principle, treating tank water by trapping fish waste and impurities in a collection chamber while returning clean water to the aquarium. 3. Saves Time: Reduces the frequency of water changes and substrate cleaning. Contains waste to help prevent water contamination and unpleasant odors, simplifying aquarium maintenance. 4. Easy to Use: Simply place in the aquarium and connect to an air pump. When the collection chamber is full, remove, empty, clean, and disinfect before returning to the tank. 5. Includes a biological filter media at the base that supports beneficial nitrifying bacteria, essential for the nitrogen cycle. Note: Requires an air pump with a minimum power of 5 watts; an 8-watt or higher air pump is recommended.
