【Filtration/ Culture/ Oxygenation】①Biochemical cotton has a high-density pores structure, which can more easily catch impurities and particles in water. ② The filter chamber is equipped with bio ceramic balls that help break down waste and cultivate beneficial stuff. ③Built-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 & Maintain】①Our fish tank foam filter includes two sponges that take the spare sponge off and stay the other on filter before use. ②Filter container is easy to detachable and can be freely replaced with any other filter media as needed. ③Hook 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. ④The sponge should be washed approximately every 2-4 weeks （use tank water rinse） to ensure the filter works properly.
