AQUANEAT 2 Pack Aquarium Bio Sponge Filter Media Pad Cut-to-Size Open Cell Foam Sheet for Fish Tank Sump (9" x 9" x 0.5") Black

Dimension: 9" Lx 9"W x 0.5"H, PPI:40. Includes 2 pieces of open cell sponges

The open cell sponge has a much larger inner surface area for filtration

This filter pad can be cut to fit and used as a pre-filter for any aquarium or pond filter, sump, wet/dry, canister, power filter etc. or your HMF DIY project.

The reticulated structure also provides better flow rate of water and less chance of clog

This filter sponge pad can last a long time. The dense structure of our sponge filter foam pad media prevents tearing, making them easy to clean and reuse.
