Thanks for the input ... I definitley go over board with the water conditioner ... Yes, I clean three times a week. I'm kind of obsessive compulsive with the fish tanks. It just takes soooo long to do water changes on 2 125's, 4 75' s, 2 55's and a 180. And that's what I have left after I got rid of a few. I'll let you guys know how things turn out. Thanks again.
