The heater in my tank seems to be either too powerful for my tank size or malfunctioning because I have it set on 78 degrees but the tank temperature is currently at 86+. I've added LR so I'm concerned about the integrity of the critters on the rock, what can I do to fix this? If this issue doesn't fix itself by tommorrow I'm just going to get a heater graded for 40 gallons.
My current heater is a 300W orca tech and I have a 37 gallon tank.
