So this morning I woke up to an electrical smell down in the basement. A Cobalt Neotherm heater had somehow melted itself and cracked open. In my refugium, on top of the water, was this brownish sticky substance. I turned off all the pumps and got as much crap out of the water as I could. I'm going to put two large bags of carbon in the tank. Does anyone else have any experience with this? I have a 180 fully stocked SPS tank and I'm hoping this heater didn't release a bunch of toxins in my tank.
