Fluval U Underwater Filter BioMax, Replacement Aquarium Filter Media, A495

Cant beat the price, i keep them on hand & use them on my many hang on back filters, & my canister filters

This product is much cheaper here than it is at my local pet store this product does everything it says

I bought this for my Fluval Edge and although it is basically loose in the box I managed to figure out a way that works for me and my tank. After rinsing it very well, before replacing the old biomax, I cut some white replacement filter foam that is way thinner than the original Fluval filter foams and fold it in there so its not loose in my grey plastic filter holder. I cant put too much because there is limited space in the holder for everything the tank needs but I get enough in there that works out well. I would recommend and buy it again.

This is perfect for everyone doing a diy filter
