Matala Biosteps 10 expandable gravity filter maximizes Matala® filter media performance. The rugged Biosteps 10 contains an amazing 200 sq. ft. of surface area for beneficial bacteria growth.

Combined with a cross flow design that traps and processes more debris at high flow rates, you get unparalleled mechanical and biological filtration for superior water quality.

Combine multiple units for large or heavily stocked koi ponds, or use Biosteps 10 with optional UV Clarifier for improved water clarity. Universal barbed inlet (1", 1-1/4", 1-1/2"), 1-1/2" outlet. Measures 23-3/16" x 15" x 20-3/16" high.

For ponds up to 10,000 liter / 2,700 gallen, step-wise transition from mechianical filtration to high-efficiency bio filtration.
