BioSmart gravity filters are packed with features and filtration capacity. The high-surface area filter foams provide exceptional biological filtration capability with respect to size of the filter. The unique design of the water flow through the filter collects debris at the filter bottom and reduces clogging of the foams. Any clogged-up foams can easily be freed up via the built-in cleaning mechanism, so there is no need to remove (and possibly damage) the filter foam from their mounts. It also makes filter maintenance fast and neat. Added features like built-in cleaning indicators and water temperature gauges round out these filters as excellent choices for smaller ponds with low fish load.

The key is in the name: A flow-through filter is fed by the pump in the water. The filter is the highest point in this cleaning cycle; from this point the water then flows back into the pond. Foams in the interior perform the actual cleaning of the water; after a few days these foams also become the home for the hard working microorganisms. The advantage of flow-through filters: They are easy to reach, they are above ground, thus cleaning and maintenance are quickly accomplished.

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 filters.
Simply shut off your pump, pull on the built-in cleaning handles and drain the sludge through the built-in drain. Quick to do and this retains the beneficial bacteria that keep the filter working. Is that smart? No, it's BioSmart!



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.
