That's certainly not true.

You can have a fluctuation of several degrees within a day as long as the tank stays within an acceptable level.

Now, it is preferable that you fluctuate as little as possible. I used to have a chiller on my 75 for a year. Then, I placed fans blowing across the tank on a temp controller.

So, I want my tank at 78:
a. if the tank goes up to 80 the fans turned on
b. if the tank went up to 81 the chiller would turn on

The chiller never went on again...

This of course is one specific case. Can you give more details about the temp levels throughout the day?
