Cleaned up my electrical
Only wires in the sump need to be and their excess is wrapped behind the sump. Don't have a drip loop set up at the moment but that's my next plan.
Got rid of one power strip by using 3 way adapters. Convenient because so many things draw so little power.
Unplugged 2 heaters and 2 koralias (replacing one of the koralias).
I now read between 2 and 18 volts at any given time. Something is fluctuating.. hard to tell what.
I no longer feel the shock in the sump, although I did try to (lol!) so I knew what the offending piece of equipment was. No such luck!
Interested to see others readings.
I know greg is and possibly meegosh or phranque.. everyone else bust out your multimeters and stick 'em in your tanks.
