i dont know to do. for the first time i have a algae problem. i have been doing my water changes when needed. when my nitrates get too high. which seems to be almost weekly. i have to clean my decorations cause they get overrun in that algae now. but it seems like dispite that every week it comes right back. one thing that has happend is three of my four snails have died. that may or may not account for all this algae. i also wonder why all of sudden they died. also today my gourami was dead. it had a bulge on its side and a big white place on its back. so far other fish are fine. anybody got any ideas what is happening with my tank???
