Question 1:my tads meter is off by 54 ppm and my tap water reads at 156, that's 210 ppm that must be added to any reading I take. My reservoir reading was 573, plus 210= 783. After I work the Lucas add back calculate I need to add 56ppm to be at target ppm. When should I worry about it? Am I doing this right?
