it is a 55 gallon have 1 canister filter, 1 powerhead , 2 t5 bulbs over the top. Still heats higher even when the lights are off. I am not sure what my problem is. Any ideas maybe 3 bad heaters in a row?
What type of thermometer are you using? Have you tried using a different one, it may be the thermometer and not the heaters? It is possible that you got 3 bad heaters but I do doubt the likely hood of that. I would try a different thermometer or if you are using a digital one replace the battery and see if that makes any difference.
