So idiot me left the humidifier on all night last night without turning on the fan. So my room was quite warm. This morning I checked the thermometer and it read 82F. I left the heater off for a while since its water change day and it went down to 80F after a couple hours, changed the water, turned the heater down to 75F, and then turned it back on after 20 minutes. I checked it a little bit ago and its almost 82F again. I unplugged the heater again now.
It hasnt done this before. I normally keep the heater on 77ishF and the temp normally stays about 79F. I know 82F is the high end of what bettas are kept in, but I dont want it to keep climbing.
The heater was turning on and heating. I could see the orange light come on for a while and then go off...even though it was set at 75F and the temp was already above that. :\
Should I leave it unplugged for a while and let the tank cool down a little till bedtime? Turn the heater down some more and plug it back in?
Any ideas on what I should do? Its a Hydor Theo 25W. And its a 5g tank.
