So i read that filter floss is supposed to help make water clearer. i have a lot of small sand particles floating around in my tank. i was wondering if i could use filter floss. i have HOB filter. an aqua clear50 and and a penguin 350. i saw the bag of filter floss at the store. looks like pillow stuffing. what do i do with it? can i use it in a HOB or is it only a canister thing?
