I waited over night, plugged in yesterday morning. The heater is set at 78 and the water has been 75 for about 24 hours or so. The temperature hasnt moved a bit from 75, which is good. I need to get a digital thermometer somewhere, we all know cheap little glass thermometers arent the most reliable, the water could be about 77 or 78, Id say the thermometer is off a bit since in the lfs they all have a different temperature. If the heater holds the temperature steady for the next few days, then Im keeping it. Thanks rus.
*Edited to add: In an earlier post in this thread, I said I set the heater a few degrees higher than what the tank water was. The water was warmed from the incandescent hood, but I shut the light off when I plugged the heater in, so I know the heater is the one doing the constant heating. Just wanted to clarify that.
