Tunze 9002 Micro Bubbles

[Coralgurl]

I'm not thrilled with my tunze at all. Mine is in my tank as I don't have a sump, have micro bubbles as well not as bad as it has been in the past, have had it since august. I don't have a heavy bio load in my tank, find I don't have to clean for at least a month and has never gotten even half full. I've adjusted it's height in the tank and dropped the water level off, if I go over the line, it doesn't seem to work.
