This morning its about 86 degrees in the house. I have two tanks, when do I need to start worring? I have the AC people coming out this afternoon to repair. Tank 1 is at 81 deg, the other I am not sure, the thermometer there went on the blink.
At 81 you're still fine. If need be you can put some ice in a baggy and float it in the sump to keep the temp down while they fix the AC unit. You can also put a fan or two on it to create evap which will also keep the temp down. I hope it's a quick fix for you.
