i have my heaters on a night timer so it'll only come on at night, it's worked great in keeping it to only a 2-3 degree fluxuation.

cause everyone lives where you live?

On an average night its low to mid 50's here. High 40's where Fatman is.

my tank has been staying around 80-81 during these hot days. In the winter it was about 78-79

Base the night time temperature you maintain on the high temperature you run during the day. You want to keep the temperature from dropping more than 1 or 2 degrees during the night. Shoot for 2 degrees difference unless you have a temperature controller, then go for 1 degree. Draw air across the water, do not blow it across the water. Moist air is dense, a fan will draw dense wet air better than it will blow light dry air. It is the wet dense air you want to move away as it carries the heat removed from the tank by evaporation. It will naturally be replaced by dry air which will accept moisture from the tank etc., etc.. Blow cool room air at the tanks glass as a dead air envelope naturally develops as an insulative barrier around the tanks glass, this will be removed by the moving air causing thermal energy (heat) to pass through the glass faster as it does also not have to now pass through the insulative still air. Isn't thermodynamics grand? The night timer idea for a heater is interesting, I never thought of that use for a timer. Sure makes sense though. Learning something all the time it seems.
