Rotafold Bio Filter (Gravity Feed Only)

Its unique design with a circular settlment tank at the base, encourages heavy solids to settle out and not be carried up into the above filter system. Filter media supplied includes five cubic feet of flocor and thirty six foam filter blocks (4" x 4" x 10" each) mounted on a manifold system.

The vortex action of the Rotafold spins water around a central drainage pipe depositing the heavy debris at the base of the pipe ready for removal. Settled water rises through the flocor bio mass and is then filtered again as it is sucked through the 36 foam bio cartridges (shown by white arrors) ideally by a Kockney Koi Wattpump surface pump on its way back to the pond via a Yamitsu UV (25 to 30 Watt).
