Humidity problems for large tank

32, wow, I'd find that unbearable.

Darryl, that switch is probably a booster fan. I have one as well (although mine isn't interlocked to the bathroom fans). It will likely help with some air turnover. At any rate, it couldn't hurt. I don't know how much power those things draw so that might be something to check into before having it on for long periods of time.

Catherine, I was really skeptical at first that the HRV would solve my wet windows but boy, did it ever fix that problem. I think I only had a tiny, tiny bit of ice buildup on my front door windows (which face north) when it hit -40 last winter for a couple days. Otherwise, my windows were more dry than other houses I visited that don't even have aquariums. The only exception was when I pulled the blinds down, they seemed to trap air in behind so overnight there would be some condensation. But otherwise it really did put a stop to having to wipe down the windows.

...yeah my tenants were...um I think the word is "special".

I've tried the dehumidifyer, and it couldn't keep up, and required constant emptying. I think the HRV is the right way for me to go, but I still need to read up and learn more about them. I'm hoping to do a rather large system, 600+g so I need to make sure it will not only meet my needs, but won't require constant servicing.
