hmmm...sounds like you are dealing with a considerable volume of liquid. 
Why try an experiment?  Fill your tank as usual, but with just plain water

at 68 degrees.  Set down and come back 15 or so minutes later and see 
exactly how much temperature change has occurred.  If you want something 
more realistic, agitate the water periodically as you would during the 
development cycle.  And if the temperature differential is only a degree
or 
two, then try one trial negative and evaluate the results.
