with my 200W heater in my 55 Gallon tank, i cannot get the temps below 79. My tank is 79 in the mornings and about 80.4 by the time the lights turn off at night. I am convinced the thermostat is busted in my heater and taht is just stays on all day. I have the thermometer set to 61 degrees now and i never see the "pilot light" turn off. I used to have to set it at 67 to get 78........
First question....are my temps too high?
Second question.....if so, what thermometer/thermostats-in-one unit it recommended? currently i have an All Glass Aquarium model, it was about $33 at my LFS
Third question.....can i just get an external thermostat? if so...recommendation??
