When I went to work yesterday my tank looked great, I got home from work and I was in a panic mode. The water had a cloudy look to it and everything was closed up. had a film on all the allot of the corals and clams. I was freaking out as to what happen, My ORP reads at about 459 to 470 all the time, It was at 310 for the first time ever. I had 20 gallons of salt water made up and did a water change. I'm thinking I have some kind of coral wars going on. Thats when I notice one of the skimmers not working. I pulled it out of the sump and the got the pump off and checked it in another room, and it didn't work, I was smelling a slight odor from the pump, not much. But later I found that the pump when I tested in the other room tripped the G.F.C.I.. I am not sure of the brand of pump. I think I will make some changes to all my tanks. No more Ph's or pumps in the sumps or tanks. I will do another large WC tonight when I get home. My ORP is back up to 415. I didn't get any pictures of the mess , That was the last thing on my mind at the time.
