Key Features

• ✅ Precision Double Filtration: hygger sponge filter consists of a circular bio cotton and a chamber base with bio-ceramic ball that provide both mechanical and biological filtration for your aquarium, which is suitable for low flow breeding like betta, guppy, shrimp, snail, and fish fry. Or as a pre-filter for other filtration systems and also be used as an auxiliary filter for large tanks
• ✅ Working Principle: This air-driven sponge filter is powered by an air pump that uses the water-lifting effect generated by rising bubbles and drives water flow through filter sponge, which can effectively adsorb excreta and residual bait to achieve the purpose of filtering and purifying water quality
• ✅ Filtration: biochemical cotton has a high-density pores structure, which can more easily catch impurities and particles in water. Culture: the filter chamber is equipped with bio ceramic balls that help break down waste and cultivate beneficial stuff. Aeration: built-in a small bubble stone at the bottom can effectively increase the dissolved oxygen content in the water and generate a lot of bubbles
• ✅ Use and Maintain: 1. Our fish foam filter includes two sponges that take the spare sponge off and stay the other on filter before use. 2. Filter container is easy to detachable and can be freely replaced with any other filter media as needed. 3. Hook the filter up to air pump, and squeeze the sponge until it is full of water making it sink to the bottom of the tank. 4. The sponge should be washed approximately every 2-4 weeks (use tank water rinse) to ensure the filter works properly
• ✅ Three Size For Choice: Small: 2.9"W x 4.1"H, it works pretty well filtration for 5 to 20 gallon aquariums with under 14” depth.
