Aquarium Advice Addict
OK, I was doing my usual PWC & noticed a shock when I touched both my fluorescent light housing (which is grounded) and the water at the same time. I concluded that there must be a short into the aquarium. I took out my voltmeter & measured 100V between the tank water & ground .... eek!
Luckily, the current is not high, only about 10 microamps, not enough to trip the GFI curcuit that eveything is plugged in.
I eventually found a busted heater (it was hidden in the sump, so I can't see it). However, after removing the broken heater, I still register 10V between water & ground (although the current is undetectable & no more shocking encounter with the light).
This leakage current is from my almost new sumersible pump (Hydor 40II - 700gph). I don't think the small leak is dangerous, but is this normal? or is my pump going too?
Well, I have to go shop for a new heater .....
