Feeling dejected. Heater exploded on Monday when I was at work. Fish are hanging in, but it looks like most my SPS is done for. Hoping my LPS hold on as well.
Well, I had my heater running through my Apex as well. It wasn't a 'stuck on' situation, but rather it shattered in the sump. My temp was never a problem, but I had some water contamination from whatever was in the heater.
Bummer too - was the it hardly was ever 'on'. I put the heater in during a cold snap last winter - but aside from those weeks - I really didn't NEED to run it in the tank.
