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.

Technical Specifications

Always rinse replacement sponges in squeezed-out aquarium water before installing into your filter caddy.

Reviews

OEM as expected! Happy to have a spare!

"Just like the original that came with my Delta 120. Always like to keep a spare of each on hand so I can change out one of the two sponges and never deplete my microbic filtration entirely."
