I've been keeping an eye on the temperature with the new heater I got, but it already says 81 degrees when I just checked to turn off the light for the night!!!! it's a 7.5w heater from petco. It looks like a round flat black disc.
Should I turn it off for the night? When I first took the temperature of the tank before putting Portal Prime in, it read 75 degrees x.x But it actually felt colder than that to me for some reason.
I don't want to bake him alive while I sleep! D:
Or, I have a suction cup for it. Is it possible that hanging it partly in the water to adjust the temperature slightly?
