I have .5 AC volts of electricity in my tank water.

Any advice. I am saving up for a grounding probe. Or can I make one?
 
It also has .5 DC volts in the water.

Thinking it is one of my two heaterrs or the filtrations water pump.
 
hmmm. try switching things off and measuring to identify the faulty gear. then replace. A grounding probe may make things worse.
 
just unplug them an test the system one by one.
 
Ya I was going to do the systematic material testing tomorrow. Felixxx thanks for that tip Ill try it right now
 
The probes touching each other don't cause a reading.
 
Not sure if you might be seeing some sort false reading. On dc does the reading flicker significantly? If you're reading a steady 0.5v on both ac and dc with everything unplugged id say you're fine.
 
also how are you testing? both probes in the water or +probe in the water and the - to a water pipe or something grounded?
 
.5 volts is nothing. It does not necessarily indicate a problem with any equipment. It's probly just induced voltage from your probe wires being near the lighting ballast or a motor. To be safe, you should always have aquarium equipment plugged into a GFCI protected outlet.
