of course something has to go wrong, things have been going fine with my tanks for awhile so its about time somethings wrong. I just posted the pics yesterday. the tank was clear before the water change. and after. and when I came home from work today this is what it looks like. the pictures make it look a lot clearer than it is. but the side view shows how you cannot see thru it! any ideas why??????
what causes this? and is it harmful to my fish? should I clean my canisters? I just cleaned them a week and a half ago.
