Is there any amount of stray voltage in the aquarium that's considered "acceptable"? It could be user error because I just bought the voltage meter and using it for the first time, but I suspect my hipargero A029 is creating some stray current in the water. Again it could be user error. When I set the voltage meter to "200m" on the DC side, I cannot get the reading to sit still if the lights are plugged in. It's typically only a few volts, but seems to spike higher too. The second I unplug the light the reading zeroes out. What's weird is I only get the reading in the water. I've tried touching it to the light itself and it's cord but don't get the same random fluctuations. I also tried getting a reading on the AC side but don't get one.
I'm digging into stray voltage because I've run out of ideas. Only one of my original corals is hanging on. I went and bought a few new ones yesterday (GPS and Xenia). Despite just a quick coral rx dip, neither looks great today. I thought maybe they're just adjusting to different parameters, but they actually looked better when I first put them in than they do now. I also recalled thinging it was strange that the GSP seemed to open up more afterhours when the lights were out while today none have come out at all. I've tested all water parameters and even added some carbon "just in case" but can't find anything wrong parameter wise.
