When you're cleaning the tank, do you drain all the water out? If you drain the water, but leave power to the heater on, the heater will get really really hot while out of the water. Then, when you put fresh cold water back into the tank and it hits the hot heater, if the heater's glass it will break. If the heater's not glass it will still overheat terrifically and could burn you or your turtle.
So the rule is.....BEFORE you take the water out of the tank, unplug or turn off the heater.
Of course I'm speaking from personal experience here. I had a similar experience with a hot light bulb....but that's another story
Much less risk with a non-glass heater like a Stealth. Also, if your heater is glass your turtle will probably express his aggression by biting the glass heater some day, with predictably bad results. That's another disaster you can avoid with a Stealth.
