My 29gal cichlid tank is at 90 degrees. I know it is the heater because it is cooler outside then the tank. I have only had the heater for about 8 months! And in the begining when i was first setting up my tank i had to replace it about 5 or 6 times. Do i need to get another heater? I called the pet shop and they told me that if i upluged it and then turned it back on it would reset itself. I tried that and it just stayed on. I have it totally unpluged right now to try and get the tank cooler.
