These small, fluidized biological filters are extremely efficient at removing metabolic waste products from aquarium systems. The unique, flat-shaped back makes it ideal for hanging on aquariums, lobster tanks, etc.
A flow control valve adjusts the fluidization level, which is easily viewed through the clear plastic sides. Bottom diffuser plate provides even fluidization and an external check valve prevents sand from clogging inlet piping.
Filters can be installed using the hang-on spring clip or the free-standing base. Biological sand media, fittings and 3' of input hose included. One-year warranty. Made in USA.
