Klir DI-4 Filter Plate for Waterbox Marine X 90.3

This custom mounting plate is designed specifically for the Klir DI-4 Fleece Filter and fits securely into the sock chamber of the Waterbox Marine X 90.3. It attaches using the Klir’s bottom screw, providing a tight seal and stable placement — no wobble, no shifting.

This plate minimizes the footprint in the sock chamber, giving you space for other filter media or live rock.

NOTE: This does not require the gasket to seal properly.
