It’s really interesting, I noticed my ORP slipped into + last couple of weeks, haven’t noticed any change in the parameters of the tank, so I figured it was no big deal. I checked the Effluent yesterday and it was the same as the display NO3… I then turned down the flow rate quite a bit, almost 50%… ORP went down and is now around -50, tested the effluent today and it’s about 1/2 of the display, hoping tomorrow it’s even lower again.
My theory is that when the No3 levels are high, you need a high flow rate to be in a safe but effective range, and as No3 levels drop and lower, you need a slower flow rate to be effective… just an observation and a theory, no idea if it’s accurate?
