Any ideas on why my heater will not go
above 82 degrees?


The higher the difference in temperature between your tank and the room
it's in, the faster it loses heat. So, to maintain a high temperature,
your heater will spend more time on than it does for a lower
temperature. When it's on all the time, that's the highest temperature
you'll be able to get. Unless you wrap your tank in a blanket, or put in
a more powerful heater.
