So I'm dialing in a new Sulfur Denitrator, about 2 months, I'm come across a werid intersection.
I've heard that you shouldn't let ORP get below -300, and that the best range for it is -50 to -150.
I'm current at -26 ORP and the nitrates in my affluent is still 0ppm at 55ml/min flow. Based on the instructions, I should be increasing flow until I get a non-zero result, but if I increase flow by just 5ml/min, the ORP goes to the positive range. The actual nitrate of the 150gal tank seems to be stable around 10-15ppm over the past week or so at the 55ml/min flow, and I'm fine with it staying at this range.
Should I do anything? I feel that I should just leave it as is. Or should I keep increasing flow even if it results in a positive ORP.
