Key Features & Benefits
Coarse 25 PPI Pore Structure: Traps large floating debris, plant matter, and fish waste while allowing high-volume water turnover without rapid clogging.
First-Stage Mechanical Protection: Intercepts heavy solids before they reach finer polishing pads or porous biological media, extending the lifespan of your entire filter setup.
Custom Precision-Cut Fit: Tailored specifically to drop seamlessly into the UNS Delta 120 filter media caddy with zero water bypass around the edges.
Durable & Washable Foam: High-resilience cell structure allows repeated rinses in tank water during routine maintenance without losing structural integrity.
Supports Beneficial Bacteria: Coarse porous structure provides additional surface area for nitrifying bacterial colonization to assist with biological stability.
