A multimeter stick the ground probe to something grounded and the other probe in the water. If the needle moves you have stray voltage. Rather it's actually killing stuff or not :shrug:Not sure what the problem is. I can see it when I click on the link. I attached a .pdf version.
My guess is was likely lighting/flow. Temp is fairly stable in the 77-79 range. I don't think it's stray voltage, but maybe. The tank is plugged into an outlet that is further down the line from a GFCI, so I figured it would have tripped. I don't know a lot about electrical stuff, so that could be wrong. What would I need to get to check that?
