Oase - Pond-Filters
The Oase BioSmart is a gravity flow-through pond filter designed for above-waterfall or waterfall-edge installation. It uses a series of foam pads in increasing density for mechanical and biological filtration, and includes a backwash handle for in-place cleaning without removing the media. The BioSmart is known for reliable performance and is one of the most widely recommended mid-range pond filters for koi ponds in the 2000 to 10000 gallon range.
