The dual sponge filter is perfect for shrimp keeping and necessary for shrimp breeding. The sponges insure that baby shrimp will not get sucked up into the filter.
This filter uses the suction from an air pump to pull water through the sponges and up through the top, with the sponge serving as a biological filter.
Each filter can serve 10-20 gallons.
Shipping for this filter is free!
