Sponge Filter CAF-250

This classic Sponge Filter is simple to install and economical to operate. The largest in the CAF Series, the CAF-250 can be used as a stand-alone filter or as a secondary filter for systems up to 250 gallons. The specially developed foam material of the sponge filter supports the colonization of bacteria, allowing for mechanical and biological filtration. The process breaks down harmful ammonia and nitrite material resulting in a cleaner environment for your fish. The CAF-250 can also be used as a breeding filter or for extra biological filtration in heavily stocked aquariums or as a pre-filtration unit. Maintenance is easy, and airstone is included.
