Yes. You might want to raise the range a couple of degrees, though, so that you go from say 83 to 80.

Assuming you use a heater I would raise its setting to 80 degrees also. Raising the floor temp doesn't always push the high temp up by the same amount in my experience. This may give you a smaller swing over a 24 hour period. If the circulation/ventilation is enough to maintain an 80 degree max then you will get a narrowing of the swing by raising your heater temp. My opinion only, but should be easy to test.

I agree with Skipper and Randy. Bump the tank temp up a bit with the heater. A 3 degree F daily temp fluctuation isn't all that bad.
