jager heater issues?

Im not shure whats going on? with your tank and heaters but one thing i would recomend doing with any new heater is to put it in a tub or spare aqarium and moniter the temp for a few days so you can dial in the heater without effecting the tank, if you get the water to warm all you have to do is cool it with a few bukets of cold water.
