Of course I have been at this for a while and back in the 60's and 70's with metal rimmed tanks and metal lights and I have been stung a few times.[/QUOTE]
I've only had tanks for almost 20 years, only been or almost zapped once. My sump on my marine tank had the return pump just below a metal halide light fighting. I was adjusting the pump a little an the return hose popped off the pump which blew a 9000 LPH stream of saltwater into the light fitting, the interior of the stand and me. I thought a felt a little tap across my whole front and everything shut down.
Not really sure if I got a few millisecond zap or just splashed and startled to be honest.
