MatalaExpandable 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 biological filtration for superior water quality. Combine multiple units for large or heavily stocked koi ponds, or use Biosteps 10 with 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.

Biosteps 10 w/Spillway makes it extremely easy to incorporate a waterfall into your pond or water garden design. Built-in waterfall discharge produces a beautiful cascade that flows directly into your pond - or create a meandering stream or tiered water course. If you already own a Biosteps filter unit, then the 11" x 7" x 7-1/2" high Spillway Upgrade is the perfect choice to enhance your pond with dynamic water movement.

Enhance your existing Biosteps 10 Progressive Pond Filter with an add-on Matala UV Clarifier. This simple upgrade lets you conveniently retrofit your Biosteps 10 or Biosteps 10 w/Spillway. Suppress blooms of suspended green algae, harmful bacteria, parasites, fungi protozoan and viruses. Also great as a replacement unit for your Biosteps 10 with UV Clarifier.
