Once the good bacteria colonize the gravel, it begins to break down the waste materials. The undergravel filters are budget friendly and work on an air pump or powerhead. These filters are primarily the biological filters. But many models showcase a cartridge that is replaceable and installed at the end of the strong tubing to offer supplementary chemical aka activated carbon or mechanical aka filter floss filtration. These filters are available for many sized aquariums but are ideal for aquariums with a light fish load.
