the redox reading on the proflux has been reading 45mv for the last few weeks,then it dawned on me that it was when i went from a very poor closed loop system to 4 tunze 6105's the increase in flow is amazing.
Anyway when i turn off the tunzes off at the wall socket and the redox returns to normal about 330mv. turn them back on and the redox starts to drop, also if the din plugs are unpluged so the pumps end up at full power the redox starts to return to normal?
