whats happening to my color / polyp ext.

[Ron99]

I battled something similar that got progressively worse for months. I checked everything and finally found out it was stray voltage. I had even checked with a volt meter but that didn't read anything. Figured it out when I stuck a cut finger in the tank.

To make a long story short, I replaced the heater that was leaking electricity and added a ground probe for good measure and had polyp extension again within 12 hours. Corals are now doing great and even a few that i thought were goners have come back.
