• 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
