Can anyone tell me of a way to decrease ORP? Most all info is on how to increase ORP, not decrease. I know that a reading of 375-385 is optimum, but I generally have it hovering about 390-400. I do not have an ozonator, so that is not my problem. I know that 400 is not extreem, but is aproaching danger. Can anyone help?
