DO NOT! use the green pads!!!! pot scrubbies are an exellent choice just dont ruin it with the green scour pads. I bought 50+ packs of these green scour pads a few years ago and they eventually break down releasing small green scour particles into the water. It is a serious pain to get out of your other media and tank. I thought i was having algea blooms for the longest time thats how green these pads made my water. They eventually lose all the green and turn white!
