Review on 🐠 Enhance Aquarium Water Quality with Fluval U Underwater Filter BioMax - A495 Replacement Filter Media by Timothy Cox

I bought this for my Fluval Edge and although it mostly fell apart in the box I was able to find a method that works for me and my tank. After a thorough rinse, before replacing the old Biomax, I cut out some replacement white filter foam, which is much thinner than the original Fluval filter foam, and fold it in there to keep it from dangling in my gray plastic filter holder. I can't put too much in because there isn't enough space in the holder. for everything the tank needs, but I get enough there that works well. I would recommend and buy again.
