I have a 37gal Eclipse 3, and I'm gettin tired of buying the replacement filter inserts. I also have a 115g filtered by an AC500 (and an eheim 2217). I was thinking the AC foam might fit the eclipse if I cut it in half lengthwise.
Has anybody ever done this, or any other diy media for an eclipse system?
