I have 2 250watt marineland visitherm heaters in my sump. they have been doing great holding the tank's temp at 77 degrees F.
All of a sudden they are not working so well and my tank is at 71 degree F. They are on, but what is happening? I tried unplugging them for 15 minutes thinking maybe there was a power surge regardless of having them plugged into the surge protector and still didn't fix it I don't believe. I will be running out to get new heaters today, but I have never had an issue with these and was wondering what is up. has anyone else had this problem?
