Thanks, that's roughly what I'd been trying to do since putting it in there (started out with near 82 when heater was set to 77) but I'd been a little worried about changing the temp too much at one time so it had just been a notch every other day. Just a little worrisome that a heater (they claim
) was designed for a smaller tank is doing such a great job keeping mine toasty - I fear coming back next week and finding a tank of cooked fish
As for the thermometer's accuracy, it usually matches up fairly well with the little LCD taped stuck onto the aquarium but then we all know how accurate those are! I know the thermometer won't handle boiling (tops off around 160) and don't know that it will read that cold, but my boyfriend has several so I can compare with those.
