So I've been looking all over the internet about using these green scotch brite scouring pads as filter media. Some sites say they work wonders some say that they are a death sentence when used as filter media. I want to use them in my aqua clear 110 HOB's as an extra added boost for bb to form. They do have the white scotch brite lettering on them if that makes a difference however they don't have any chemicals on them as far as I know... So am I able to use these as filter media or should I stay away from them. I've already purchased them but haven't put them in my HOB's yet. I've also purchased round mesh scrubbies too in a 3 pack can I use these ?? If both of the scotch brite scouring pads and the round mesh scrubbies are no good what other things can I add to my HOB's to make them more efficient and get max efficiency thanks to all replys in advance

The multi colored cheap pot scrubbies are the ones to get.
