45 gallon too cold

I need a little help with my temp. I have 2 heaters in my tank and it is STILL too cold. On is a 200W and the other a 300W. The tank is Hovering around 62 degree's (unless my thermometer is way off). I have tried shutting off both heaters for a half an hour to recalibrate, but no dice. One has a built in thermostat, and the other does not. How can I get the temperature up to normal???

How warm is the room you're keeping the tank in? Even if the heaters aren't working, the tank should be room temperature and 62 is a pretty cold room. Are there fish in the tank?

1. Check the tank with another thermometer. An instant-read meat thermometer can be used, or buy a second thermometer. They're cheap.

2. Try plugging a lamp into the socket you're using for the heaters. It's an easy way to make sure you're getting juice to the heaters.

3. If your thermometer is reading correctly and you're getting power to the heaters and you're not housing the tank in a meat locker, I'd suspect your heaters are shot. A single 200W should probably be adequate for a 45g tank. Get a good heater with an adjustable thermostat.

yep try another thermometer, 200w should be enough. If the thermometer is reading right then I would get a new heater the thermostat might be bad.
