Helix Bio-Mechanical Reactor Waterfall Filter - Large

The Helix Bio-Mechanical Reactor combines the efficiency of The Helix Moving Bed Waterfall Filter and The Helix Bio-Mechanical Waterfall Filter, to improve the water quality and clarity. It provides a large open area for lava rock media without bags that typically would reduce flow rate. Made of a heavy-duty rotational molded HDPE construction. The stainless steel hardware and high quality plumbing parts are made to extend the filter's life. The biological media can convert the digested waste for 3 pounds of fish food each day. It includes an air manifold for air-assisted cleaning and a 2" Bulkhead (Not pre-drilled, so that you can chose right or left side). Does not require a lid, so can be covered by a large stone or faux rock. Includes two check valves and a separator screen for optimum flow, a 3/4" outlet bulkhead and two knife valves to open drains for cleaning.
