TetraTec BB Bio Filter Balls are biological media that provide an excellent environment for friendly bacteria to break down ammonia into harmless nitrate. Because they are not too porous they allow a good flow of water through them, which ensures that all the bacteria receive a supply of oxygen and nutrients. This keeps them working effectively, and avoids dead areas. Clean in aquarium water only, as and when necessary |
