During the day my tank (90 gallon) ranges between 78/80, but recently I've noticed that it has been at 84/86. I have not used the heaters. I've noticed if I try to regulate the temprature with the heaters it gets even hotter. Please help!

That's pretty unusual heater behavior. How many are in there and what models? Where are they placed and what temp are they set to?
