What are some different kinds of filters?
      Either air or electricity can be used to move water through the filter. One commonly used filter is called a power filter. The electricity runs a pump which in turn pushes water through the filter. Filters provide a surface for bacteria to grow. This helps in biological filtration. Filters often include carbon for chemical filtration as well as material for mechanical filtration. Some tanks also use sponges as biological filters. Sponges provide substrate for bacterial growth and encourage biological filtration.
