So today I got a little zing from the DT while I was doing a water change. :spin2: I got out my multimeter and found that I had about 27 volts of stray current. Through the process of elimination I pulled out a heater that was leaking and I am down to about 13 volts.
Here's the question, what level of stray current is acceptable? When I unplug one item at a time, I notice that the voltage drops about 1-1.5 volts and returns when I plug it back in. Is there an acceptable threshold, or do I need to systematically replace every pump, powerhead, heater, etc until I have it close to zero?
FWIW, the frag system is down to 6 volts after pulling out a simillarly aged heater. (Don't need them this time of year anyway)
