I saw a bottle of "Easy Balance" made by TetraAqua at the lfs yesterday. It purported to help eliminate the need for water changes. From what I remember reading on the back, you just put in a certain amount every so often. According to the bottle, you only needed to do a water change every six months (if I remember correctly). Has anyone ever heard of or used this product? It sounds a little to good to be true, but then again, it is just chemistry
