Replacement Sponge Hack for Aquarium Co-Op Sponge Filter

Erik W.

Recommended Posts

Hi everyone!

I needed to modify my large pre filter sponge to fit my surface skimmer attachment. I cut off what wasn't needed and thought how it looked like a small Aquarium Co-Op Sponge Filter replacement. I have a spare small sponge filter from the co-op so I decided to try it out and it works!! I apologise if this is common knowledge but I wanted to pass this along to anyone who's lost or ruined their sponge and couldn't find a replacement. FYI the pre filter sponge seems to not have as many pores per square inch and I have not tried it on a bigger filter size than a small. I hope this helps!

All the best,

@SarayParay The more pores per square inch(ppsi) you have, the more it removes debris from your water. For example, if you have 50 ppsi you would catch more debris than if you had 30 ppsi. However, higher ppsi require more maintenance as they clog faster. I believe the sponge filter media is 30-35 ppsi and the pre filter media is 25-30 ppsi
