Are you still bothering to clean the fish tank or Aquarium?
With this sponge filter, you will offer your baby fish a healthy and clean environment easily.
Sponge filters provide both mechanical and biological filtration.
Simply install an air pump into the unit and provide both aeration and filtration for your fish.
Aerobic bacteria colonize the sponge providing a bacterial substance to facilitate the nitrogen cycle.
In addition, the sponge traps larger waste particles mechanically cleaning the water without trapping baby fish.
They are used as breeding filter or as secondary filter. Or they can be used as pre-filtration unit by fitting to an external or a top filter.
