Tank Shock?

[jk1151]

Hey all - I have had my tank up and running for a year now. I have a grounding probe installed. Today, however, I noticed that when I was putting new RFAs in to tank when I first touched the water I got a little shock. I haven't noticed that before. It takes awhile for it to build back up and actually seems to go away when I have everything running. I was only getting shocked when I had the tank on feed mode and pump was only thing running at like only 20%. I was going to check for stray voltage but wondered if anyone had any different ideas? I didn't think I should get shocked with a grounding probe in but maybe I misunderstood? Can grounding probes go bad or need cleaned? Could this be the issue. Thought I would check as I begin working through this issue. Thank you in advance for any replies and suggestions.

I would start unplugging items one by one until you find the culprit . My guess would be heaters.

ok- will do. I had them off when I was getting shocked though. I had everything off except the return pump. After turning it off I also felt a little shock. So am I to assume that even if you turn off everything with your apex you can still be getting stray voltage? Also, what voltage would be appropriate to see in a tank as I believe there should be some reading on my multimeter but not sure what level is a worried level.

Do you have a GFCI plug for the tank? A small shock can turn into something much worse. In my opinion you should not have any voltage in the tank water. I consider anything approaching 50 volts to be dangerous. Test for both AC and DC voltage.

Are you sure you don't have a little cut on your finger? That's happened to me.

Try saltwater in a glass and see what it feels like - or better yet use a volt meter (multimeter).

You should also know if there is stray voltage - you don't want your life to depend on a grounding probe.

ok - getting a multimeter later today and will test. Yes, on a GFCI and have a grounding probe. I have tried multiple times and cannot get shocked once tank is up and running. Only getting shocked when I have things turned off or just the return pump running.

Will do thank you. Yeah, no cuts nothing. I am super flabbergasted (couldn't think of a better word). I researched a ton and read a lot of forums before posting. At this point I have tried everything except a multimeter but heading to buy one here in a bit. Thank you for your response!
