I replaced one of my heaters just to be safe. I bought the heater from BRS and it is the kind that needs a regulator. I plugged it into the port that housed the old heater. About three hours later the lights on my tank went out. In checking out the problem I found the temp at 84. Obviously the Apex had not regulated the temperature as it had on the old heater. Any suggestions where to go from here to fix this problem? Thank you.
