Asternia stars. now with solutions, and stray voltage

[Reef Pilot]

I do my stray voltage testing at the 10 setting, and if the needle moves at all, I know I have a problem. Then it is just a process of elimination to find the culprit device.

I have found a couple mag pumps that moved the needle slightly. But the worst was an old T8 light fixture that was on top of a QT tank, and somehow the voltage would get down into the water. I am not using that one any longer.

I now test all my tanks, and sumps, and use the Rid Volt grounding plugs.

I found over 50v in my 125g FW tank. It was 2 Maxijet 900s and 2 300w Smartheaters causing it.
The only thing that will be 'wet' in my new 75g will be the skimmer pump. Even the heaters will only be up to the water mark.

thats kind of a PITA hey when you buy stuff, and it causes problems for what ever reason, and of course the store wont take it back for exchange lol
