An economical three-stage filter. Debris is first strained out by the filter brush, then a profiled filter sponge traps most remaining particles. Finally, water passes through bio-media where beneficial bacteria thrive, removing ammonia and nitrite.

The revolutionary design of these filters combines mechanical filtration and biological filtration to guarantee clear purified water. Periodic filter foam rinsing & foam replacement is the only maintenance required. Attractive green color blends easily into landscape.
