Stray Voltage

[Zbass]

IM showing about 7.8 stray volts in my water in my 15 gallon AIO reef tank. my corals have been closed for weeks and I have tried everything, this is my next thing im trying to check. would this cause them to stay closed?

7.8 is very little probably normal residual. Also stray voltage doesn't harm tanks I habitants. I've had as much as 50 volts before and everything was fine except me when I stuck my hand in. People who say stray voltage harms animals in out tank are just repeating what they heard or read.
