One of my glass heaters in my sump broke sometime last night and I didnt even check my tank this morning as I left for work since I was running late. My g/f called me at 2:00 this afternoon to tell me I had two dead fish and none of the pumps or lights were working. The broken heater tripped both GCFI's that all equipment is plugged into. I helped her find the problem and get some pumps running until I got home just a bit ago. I lost my sailfin tang and my little fuzzy dwarf lionfish but the eel and two spot tang are still doing ok it seems and all inverts from the clam to the xenia are open and looking normal. With it down to 71.4 degrees how much damage will this do? How should I go about bringing the temp up or should I just let it climb on its own even though it will take 24hrs or so to bring the total 120gallons of water back to normal. What should I do????
