The BioSteps 10 Filter, without UV, combines both mechanical and biological filtration for better water quality. It contains 200 square feet of surface area for beneficial bacteria growth and has a flow rate up to 1,060 GPH per unit. Multiple units can be combined for larger or heavily stocked Koi Ponds. The BioSteps 10 features a cross-flow pattern to trap more dirt at high flows without plugging up and has a sloped bottom with an extra sink outlet for an easy draining of waste.
PLEASE NOTE: Optional UV Clarifier and Spillway are not included. Each optional item is sold separately and is not needed for the BioSteps 10 Filter to function.
