dangros August 25, 2019 Share August 25, 2019 While working on the tank, I felt a slight sting in my finger which I took as an electric charge. So I took a multimeter, stuck the red probe in the water and the black probe in the ground/3rd hole of the outlet. Sure enough, I got 30V on the multimeter!! I systematically turned off each electrical item in the tank but the multimeter never dropped to 0. Removing some pumps seems to drop or even increase the current but I'm assuming that they are acting as poor grounding probes when they are off which may explain why I see current dropping when I restore them... In any case, I'm very confused and worried that I may have a dangerous situation. I have a grounding probe which helps but obviously isn't the correction I'm looking for.

MODreefer August 25, 2019 Share August 25, 2019 Check your heater. Also, remove anything with an electrical wire from the water. Good luck. Link to comment Share on other sites More sharing options...
ImGoingCoastal August 25, 2019 Share August 25, 2019 Do you have an electric eel?! I kid.Why not try the reverse. Unplug everything to ensure the drop off to 0, then plug items in and note anything that raises it.-A-a-ron Link to comment Share on other sites More sharing options...
dangros August 25, 2019 Author Share August 25, 2019 Thanks MODreefer. This video explains why I couldnt find it. (he has an ad in the middle of the vid, you can skip by fast forwarding) Link to comment Share on other sites More sharing options...

That doesnt really help b/c each item adds some AC voltage so it's difficult to locate the actual leaking device.

Origami August 25, 2019 Share August 25, 2019 Maybe a grounding probe will help. Sent from my Pixel 3 using Tapatalk Link to comment Share on other sites More sharing options...
treesprite August 26, 2019 Share August 26, 2019 There have been many times that I have momentarily mistaken a sudden zap or tingle as electricity and then discovered a paper cut, cuticle tear, or other miniscule flesh wound that reacts adversely to submersion in saltwater. I have had real electrical leaks and the feeling is identical. Now when I get that feeling, I examine my hand before I go checking all the electrical devices.

dangros August 26, 2019 Author Share August 26, 2019 (edited) So I found out that most of the electrical readings are due to induction. The problem is, I have no cuts and I did feel it that one time. placing my fingers in salt water does not create that zap feeling. It only happened once and it was in the basement. I’m starting to think there is no leak and it was something else but I can say for sure that it was NOT a cut and it happened when salt water ran out of my DoS hose. I will continue to monitor. At least my probe is now bringing the induction current readings to 0. Edited August 26, 2019 by dangros Link to comment Share on other sites More sharing options...
treesprite November 13, 2019 Share November 13, 2019 Maybe you have a nerve problem, carpal tunnel or something that would cause a tingling feeling when hand/wrist is used in certain positions (another thing that happens to me). Link to comment Share on other sites More sharing options...

No I don’t. The only nerve problem I have is keeping my nerves when stupid stuff like this happens. It’s probably my return pump. It went bad and am replacing tonight, actually.

treesprite November 14, 2019 Share November 14, 2019 Good luck with the new pump. I hope that solves the problem. Link to comment Share on other sites More sharing options...
Brian M November 19, 2019 Share November 19, 2019 I have been getting shocked in my tank too, not everytime but enough that it is concerning. I just noticed my hydor koralia pump had seized up and when I went to purchase a new one read reviews about other people getting shocked by these pumps after a few years of using them. I am now looking into purchasing either the (2)Jbj oceanstream circulation pump 1600 gphOr(2) Tunze 6055 controllable pump.I have a 75 gallon tankLet me know which you recommend.Thank youBrianSent from my SM-G950U using Tapatalk Link to comment Share on other sites More sharing options...
paul b November 19, 2019 Share November 19, 2019 30 volts is induced voltage and not anything leaking. If something was leaking you would get 110 volts and you would be thrown across the room. 30 volts is normal. Any electrical appliance near the tank will induce voltage. Those people with the purple Mohawks you see spent a lot of time walking under power lines and it fried their brains.

AlanM November 20, 2019 Share November 20, 2019 I've gotten a tingle from failed Jebao powerheads before. It's not a lot of voltage, so it didn't launch me, but I could feel it for sure. Link to comment Share on other sites More sharing options...
