My temp has been licking 80 the whole day yesterday and I'm thinking of hooking up another fan and buy 3 more gallons of RO for my top-off just to keep it where I want it in 78; to those with a/c or central cooling, you are very lucky.

My tank is in the living room, I have the 2 stock fans in the lighting fixture. I also have my cieling fan running all summer, Never thought about it until you asked where the tank was located. I keep my house around 75 degees.nyc reefer: from what I read online, to be on the safe end it shouldn't pass 82; probably around 78(?). Mid 80's seems to be working fine for Greg; as long as it's consistent, it should be fine I guess.
jaa1456: where do you have your tank and do you have a fan? 78's a pretty nice comfortable number.
