I was in the middle of some maintenance on my tank and I had a few components in a bucket for cleaning. I noticed that the wire for the micro pump on my Innovative Marine UV had a white mark on it so I moved it to look closer and the wire cracked to dust in my hands. The wire was definitely severed before I took it out as it was extremely frail and therefore it must have been leaking electricity into the tank. This is the same as cutting a lamp cable and putting the wire in your tank and then plugging it in. The pump was only about 5 months old too. I am really at a loss for words on how my tank survived like that and pretty mad at IM for selling a product that cheaply made. I have been having some trouble with corals for the past couple months - nothing too bad really (mostly just STN on some SPS) and I noticed since removing the pump that all of the corals look much happier (better PE and coloration change in only a few days). The fish seem the same as usual although they are hard to get a read on considering they're fish. I feel terrible for not catching this sooner and the thought that my fish were being electrocuted for that whole time. Please be careful if you are running one of these!
