Oase BioSmart Gravity Filter

This item is eligible for FREE shipping!
SKU: OAS/40353

The unique design of the BioSmart water flow through 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.
