I'm not speaking for Bob. I'm an intruder here.
My concern would be the temperature swings over the course of an hour rather
than the course of a year! The term is hysteresis and typical cheap
thermostat mechanisms cause a lot of it. The heater doesn't come on until
the temperature is 4 degrees too low and then it doesn't quit until the
temperature is 4 degrees above the setpoint. All in all in an acceptable
range, perhaps, but how fast do temperatures swing on a tropical reef? How
fast in a 6 gal. nanoreef?
I don't know the answer to that question but I would like to!
I *suspect* that temperature swing (hysteresis!) in a nanoreef can be rather
extraodinary and stressful to the inhabitants. A serious thermostat control
may be of benefit.
But then - I don't know ;-)
