Copper Test Kits -
So while Red Sea makes "a better, the best" salt, they are not good for thier Copper Testing... That figures since it was the only one the LFS had in stock last night!
So who makes the best Copper test kit?
But I read that copper was an issue for fish and inverts - I've not (knock on wood) had any issues with fish/inverts. Could a higher level of Copper cause issues with SPS but nothing else in the tank? I'm willing to test anything just to eliminate other possibilites.
As for elictrical -
I stripped the tank down (unplugged everything) and one at a time plugges stuff in. I was getting the 40 volts (yes forty) when my Profilux controller was plugged into the wall outlet and nothing else was plugged in... But I also had my laptop pugged into communications port on the Profilux and the power supply for the laptop was not plugged into the wall (but was plugged into laptop). I plugged the lapto power supply inot the wall and tank voltage zeroed... I removed the laptop and left the Profilux plugged in = no volts.
So there is something wrong w/ laptop when its attached to Profilux, has power supply attached, but not plugged into wall. I'm relieved to find it was NOT the Profilux and the laptop belongs to work so thats another issue... For now, I leave the grounding probe in the tank and either ran laptop on battery or plug in the power supply. Still dont completely understand it because all this means is the laptop was putting voltage into the Profilux and Profilux was passing it to the tank via one of its probes. It got Temp,, pH, and Salinity probes plus water level sensor - I removed all probes and voltage is stilll there so it must be passing via the water sensor some how. One weekend I'll have to try another computer and see if results are the same.
I'm not sure the voltage was the issue because the laptop doesnt stay connected, once a week when I do maintenance (WC) so it would not have been a continuos thing.. But who knows. I have noticed that my clown fish no longer get the shakes while swimming so the ground probe must have fixes something and one of these days I'll know for sure just how/why....
