BioSmart Flow-Through Filters

BioSmart Flow-Through Filters Next generation flow-through filters

The BioSmart Gravity Filters are a multi-stage mechanical and biological filtration system in a compact package, designed for medium ponds or for ponds with moderate biological load (some fish).

During biological filtration, the water is channeled through a series of filter foams that create a special environment by allowing the settling of beneficial bacteria. During this stage, harmful ammonia and nitrites are converted to nitrates, which support plant life in the pond. 

Low Maintenance and High Functionality

BioSmart Filters are packed with features and filtration capacity. The high-surface area filter foams provide exceptional biological filtration capability in relation to its size.  With features like built-in cleaning mechanism and water temperature gauge make BioSmart Filters an excellent choice for smaller ponds with low fish load.  

Distinct Filter Zones

BioSmart filters feature distinct zones that promote the settlement of the beneficial bacteria responsible for different phases of the nitrogen cycle, increasing the conversion of harmful ammonia in the pond.

Built-in Cleaning Mechanism
No need to remove or manually unclog the filter foams of the BioSmart filter. Simply shut off your pump, pull up on the built-in cleaning handles and drain the loosened debris through the built in drain. Quick to do and this retains the beneficial bacteria that keep your pond healthy.

Advanced Features

The cleaning indicator, along with the temperature gauge and sludge drain are just some of the features that make BioSmart the most user-friendly and easy to maintain entry-level pond filter ever designed.

Clear 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. » Learn more «
