I looked in my tank for the first time in 3 days and saw that my corals were not opening. On of the power heads wires was putting off bulbs into the water. I have a stong smell of low tide my skimmer is working double time. Fish are fine Sea urchin looks dead. My hammers are all closed, my caps are turning white. I unplugged the power head. What next cross my fingers or do a massive water change? Working with a 120 gal tank by the way.
