Temp help

[currentking]

I've had my aquarium set up for a few months and the temp stays between 78 and 80 consistently when my ac is set at 78. The last 2 days it's been hitting 81 and I have my ac at 75. I have 2 radion gen 2 pros on the tank. What is the first thing I should check for the added temp? Thanks for your help

Check your heater if you run one, next would be a pump that's locked up.

Your heater could be going bad. I'd set up a new one in your tank and recheck the one you think might be faulty in a bucket of water.

check your heater

Check with different thermometer.
Closed canopy? Fans?

81 degrees isn't even bad
