hi everyone
i am new fish keeping and trying to make a DIY PVC canister filter for my 25g tank. i am looking for a cheap and easily available bio filter media to put in my canister filter. my question is: would this make a good bio media filter? what would u guys use as media in a 4" PVC diy canister 1ft tall?
