Right now i have the probe need one uth with both of the heating pads plugged into the thermostat with a 3 plug surge protector. The heating lamps I only use at night right now and I’m using the blue “night time” bulbs. I just wasn’t sure if this was a good idea. I forgot the wattage on the uth, I will have to go back and check. Both are for 10-20 gal tanks. Thanks to both of y’all for the advice.
