The Pisces Compatible Filter Foam is designed for pond owners who use Oase BioTec 5.1 or 10.1 filtration systems and need reliable, high-quality replacement media. These coarse-grade foams excel at capturing solid debris to keep pond water clear and healthy, though users should note that they are specifically engineered for mechanical filtration and do not replace biological media. This twin pack offers a cost-effective maintenance solution with easy-install features that ensure your filtration system continues running at peak efficiency.

No, these foams are specifically sized for the BioTec 5.1 and 10.1 units only.
Depending on your pond environment, they should generally be replaced every 6 to 12 months or when the foam loses its structural integrity.
No, machine washing will destroy the structural integrity of the foam. Rinse only in a bucket of pond water.
No, this product consists entirely of coarse-grade filter foam.
The blue colour is specific to the Pisces line and signifies the coarse density grade for identification purposes.
Ensure the foam is pushed completely onto the rack and that the edges are seated tightly against the filter housing.
Check if your pond has an excess of floating debris or overfeeding; rinse the foam more frequently or add a pre-filter.
Verify you are using an Oase BioTec 5.1 or 10.1 unit and ensure no debris is stuck in the filter rack channels.
Installation is straightforward due to the pre-cut slits. Simply turn off your pond pump, remove the lid of the BioTec filter, pull out the old foam cartridges, and slide the new Pisces foams onto the support racks. Ensure they are seated firmly against the housing wall to prevent water bypassing the foam. To care for your foams, rinse them periodically in a bucket of old pond water. Avoid using chlorinated tap water, as it will kill the beneficial bacteria colonies living on the foam surface. Over time, as the foam loses its elasticity or begins to crumble, it should be replaced to maintain consistent mechanical filtration.
