New China Shop Topic: How Accurate is the Pool Calculator?

[CarlD]

Which of the water balance parameters require 0.1 ppm?

Or, coming at it from another way, do the many variables we've both enumerated need an accuracy consideration to 0.0001 part per billion? Can we even measure that?

Don't you mean 1 part per billion (1/1000 of a million).

Of course none of the majors do (pH doesn't really count). The lowest we EVER need to go is .2 (useful if CC is not clearing properly).

But you are defending a known, fixable inaccuracy in the system.
