My First Tank

[Delphinus]

Actually, I'm glad you mentioned that. I'd be having the same concern if it was my tank. If your tank is 27 when its 21 in the house, what's going to happen when it's >30 outside? Do you have A/C? I know it doesn't get >30 all THAT often, but it does happen. I'd be keeping a half a thought process on this in the next little while, you have a few months before it's a real threat but it's nice to have a contingency plan if it does happen. My house gets crazy hot in the summer so this is something I have to deal with every summer. I typically deal with the heat with extra fans blowing on my sump, does a bangup job but it increases the evaporation like crazy so you need to be on top of the top-up. The only issue with fans is that you really DO want a heater because if you get too much evap you can actually pull your tank temp down too low. So you definitely want some kind of balancing act there. Just my $0.02, hopefully not a really huge deal but like I said it's something I think I'd be thinking about if it were my tank.
