The best filter for your shrimps tanks.

Dual Sponge filters provide both mechanical and biological filtration. Simply install an airline 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 useful for as breeding filter for small fries fish and shrimps since they provide more oxygen in the tank.
