Have you checked for stray voltage lately?

Good idea to point that out. I actually had the exact same issue with my lights. It was bad enough that if my arm was in the tank and my elbow touched my light I got shocked. Didn't realize it was the timers. They only were made for 2 prongs so I just drilled out a 3 hole for the ground. Didn't know what it was until I got my apex and no longer used the manual timers.
