I had a water bed leak steadily drip into a power strip. Imagine my surprise when I wole up tho the intermittant sizzling sound......shhzzz shzz shzzz shzzz. "whats that, smoke ?" AGHHHH.! The strip was all melted and mangled looking but it never stopped supplying power! Good thing Rubber waterbed bladders dont conduct electricity. lol Yikes.... Hope everything is good with your tank.
