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
