Dual Sponge Bio Filter

Providing mechanical AND biological filtration, this system is in almost everyone of our tanks. We love them. You need not worry about young/baby shrimp being sucked into any filter intake with this design.

Best of all, the beneficial bacteria love the sponges and will colonize quickly, helping your tank cycle even faster and/or maintain the beneficial bacteria.

Great for up to a 20 gallon tank.
Simply add an airline and your ready to go!
