fish tank with power head, possible electrical leak?

[yuyuhjkdsuyy]

Hello all

I have a fish tank with a submersible water pump that would supply water to the overhead filter. When i tested it the water with a eletronic test pen, it shows that theres 36V current. ( AC i think, i am no good with these)

Is that a leak or is that common to have some current when a pump is in? my catfish seems fine in it.

should replace the pump, i am not sure if the new pump wont have this problem.

thanks in advance

I would look again at the reading and what it is you're testing as what you posted doesn't make sense. if the fish is happy and you didn't get your hand blown off it can't be that bad.

hello Ken

thanks for your reply. i am using a multi functional digital tester. its like a test pen with a digital screen read out, just got it recently. I dipped the tip of the tester into the water. its something like this

What is it actually measuring though? Its probably not measuring any leakage at all. (It only appears to have one connection so its using induction of some sort. It will probably detect it if you hold it near the powerhead outside the tank.)

The fish will swim around quite happy even with a mains extension in the tank, I know that from experience. It does tingle when you reach in to get it but its not painful. You will probably remember to turn the mains off next time. I certainly remember now and it happened 38 years ago.
