Tank temps

I have always been under the impression that any fluctuation was bad, but I guess that if I was using a mercury thermometer I doubt I would even notice the fluctuation. I am using the Coralife digi thermometer.
I will continue to keep an eye on ethe temps.
Thanks

You could use a controller, but not worth it IMO. You could also try a second heater, that would stabalize it a bit.

My heaters do the same thing, fluctuate a bit, stay on late and go off early. I go from about 78.5 to 80.5 right now. Your temperature range is fine though, in fact IMO I think it is perfect.

stable tank temps are important, a controller is a good way to help keep a heater do what it should. you can get a ranco controller for pretty cheap.

How stable is stable?
What is an allowable range?
I really dont see my self spending $100 for a controller unless my temps are really out of whack.

IMO A temp controller is the second most important piece of equptment for your aquarium. there a little pricey... But last year i went away for three days to come back to find my tank at 89F

one of my under powerd heaters (ebo) had stuck on all i was left with was 1600.00 of Reef Soup. The $$$ i could Have spent on the controller could have saved me $1600.00
its almost sicking... Oh well live and learn PLEASE LEARN FROM ME BUY A TEMP CONTROLLER.

We dont even run a heater in the 180gal, when lights are on the Temps are around 82-83, lights out the temps are 78-79 just like in real life

You must be running a lot of (or large) submerisble pumps then?

I bought the same one and found that it was a POS from the first day I put it on.

I checked against a Raytech infra-red pyrometer and the coralife digital thermometer was allways out at laest 3 degrees one way or the other. (Maybe I just got a dud?)

I wouldn't trust that thermometer IMO.
