The Pisces Replacement Filter Foams are essential maintenance components for Oase Biotec 12 filtration systems, designed for pond owners who prioritize clear, debris-free water. These coarse-grade blue foams excel at mechanical filtration by trapping algae and larger particles before they can clog the biological stages of your filter. While these foams provide excellent debris capture, users should note that they require regular manual cleaning to maintain optimal water flow rates through the system.

Typically, you should replace them when they can no longer be cleaned effectively or when the foam loses its physical shape and ability to trap debris.
No, these are specifically sized for the Oase Biotec 12 and may not provide a secure fit in other models, leading to poor filtration efficiency.
Tap water contains chlorine and chloramines which can kill the beneficial nitrifying bacteria residing in the foam, potentially disrupting your pond's biological cycle.
No, these are coarse-grade foams meant for trapping larger particles and algae. They will not clear up fine, cloudy water on their own.
While not strictly required, it is often best to rotate them or replace them together if they show equal signs of wear to ensure consistent filtration performance.
The foam is likely saturated with debris. Remove and rinse thoroughly in a bucket of pond water.
Ensure the foam is pushed completely down the filter handle and sitting flush against the base of the unit.
Verify that the filter handle is clear of sharp buildup or calcium deposits that may be snagging the foam material.
Installation is straightforward due to the pre-cut slits: simply remove the old, degraded sponges from the filter handles, slide the new Pisces foams into place, and ensure they are seated securely against the frame. Compatibility is strictly limited to the Oase Biotec 12; do not attempt to force these into smaller or larger filter models as this will result in water bypassing the media. For care, always rinse the foams in a bucket of pond water rather than tap water to preserve the beneficial bacteria colonies living within the foam structure. Replace the foams entirely when they begin to lose their structural integrity or no longer spring back after being squeezed.
