When we bought it the directions say to only turn it 1 notch at a time. The thing of it is there really are no "notches" so we have a guess.
The temp in the house goes up and down, mainly because I don't like it to hot. The heater does it's own thing and doesn't regulate.
The heater I have is one that hangs on the back of the tank. I forget the brand, but I'm sure it isn't the best.
Please give me advice on which heaters are the most reliable at maintaining the same temp. day and night. I'm getting tired of fiddleing with the heater 4 times a day.
Me and the goldies thank you.
