that's what I've been thinking about. Gosh this tank is costing me more than I expected
We leave the door to the room closed during the day - we've got 4 cats that would cause rather insane amounts of chaos in the bedroom if we left it open - but I know that's a part of the problem, too.
I'm going to try a few more things, I'm going to keep the surface fan on a timer as well.
How does everyone hook up the PC fans easily? Is there a transformer that will convert the power connection to a standard AC power?
