Complete biological and particulate filtering in one compact package. Connect to any submersible or centrifugal pump on the intake side and drop into a tank or pond for instant filtration. All plastic construction with 3 1/2" O.D. (4" w/sleeve) and 1" PVC pipe ends. Use PVC pipe and fitting to make your own multi-filter manifold.
We also offer them pre-filled with either coral, lava rock or activated carbon. For heavy duty biological filtering, we recommend one inch of filter length per gpm.
Coral cells use Florida crushed 3–4 mm coral, great for pH buffering. Activated carbon cells use coconut shell carbon for polishing the water crystal clear. The lava cells are for applications where large amounts of waste would foul conventional filters, such as koi ponds.
All cells come with thick, Dacron® pre-filtered sleeves. Media can be easily removed for cleaning. Add your own media to the empty cells. Made in USA.
