Hey all, I`m new here, and fairly new the hobby. I`ve had several 10 gallon set-ups, but i just upgraded to a 33 gallon tank. I`m aware of cycling the tank, and all of that sort of stuff... But I have something that may be a dumb question.. just cant find answers anywhere else. Is there such thing as too much aeration?? I have an AquaClear 300 filter, and a Hagen Optima 807 Air Pump. I have the pump turned down quite a bit, and it is running a 10'' air stone, as well as a 4'' round ''volcano'' air stone. The bubble's are fairly large, I expected more of a fizzing effect, but the fish don't seem to mind them at all. I just don't want to over do it. Thanks for any advice you have to offer. Chris.
