The BioSmart is a flow-through filter that is both innovative and efficient. It undertakes both biological and mechanical filtration and offers maximum oxygenation. With a sludge drain that makes for easy removal of coarse debris, the BioSmart is built for work - there is no need to remove or manually unclog the filter foams. Distinct filter zones promote the settlement of beneficial bacteria responsible for different phases of the nitrogen cycle, increasing the conversion of harmful ammonia in the pond. When used in conjunction with the BioSmart filter, the AquaMax Eco Classic 1200-2700 or AquaMax Eco Premium 2000-3000 and the Vitronic UV Clarifier qualify for the OASE Water Guarantee.

When a pond owner uses specifically marked CWG products, they are guaranteed to have clear water and minimal maintenance. We guarantee that when a tape measure is placed vertically into the pond to a depth of 3 feet, the water will be clear enough to read the 1 inch mark at the tip of the tape measure.
