AQUANEAT Aquarium Bio Sponge Filter Media Pad 36" x 12" x 1" / 72" x 12" x 1" Open Cell Foam Sheet Cut-to-Fit for Fish Tank Sump (36" x 12" x 1")

Dimension: 36"" Lx 12""W x 1""H, PPI: 40. Please note, this filter sponge is vacuum-packed; it expands to full size after 10-minute water immersion. 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. Traps large bits of waste and provides better water flow rate 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
