the7thchemist said:The topics that are not taught in the CPO class are far greater than what was shown in the post.
The question is: Will the program begin to prepare me to operate a pool properly? The operative word here is 'begin'.
The answer is that the CPO program never asserted that it was exhaustive. It is sufficient to begin.
The collective experience of the members on this site can find fault with anything. Here, I find fault with the nit picking of a good program, written by an industry expert in 2005, and reviewed by many other industry experts.

The use of the term “reserve” is not a standard one and without user definition its use is not warranted. Comment appears to be based on information provided in a 40-year old reference. This is a definition, and does not need to be an in-depth, page-long article. Current code language is preferred.
The O’Brien paper relies primary on the use of computational techniques with only limited conformation using wet chemistry analysis. The straightforward derivation described in the comment is not obvious. Further research is necessary to consider this proposed language.
Experimental evaluations of K were based primarily on ultraviolet (U.V.) spectrophotometry, i.e., techniques such as differential spectrophotometry and spectrometric titrimetry. Fundamentally the particular measurements performed exploited the often large spectral differences between "adjoining" species such as: (1) cyanuric acid and its successive ionization products; (2) chlorinated cyanuric acids and their successive ionization products; and (3) chlorinated cyanurates and their successive hydrolysis products.
The computer program was of great assistance to the experimental studies. Computed estimates of species' distributions obtained from preliminary values of the equilibrium constants were invaluable for establishment of the conditions and concentrations that would appropriately restrict the number of significant species in subsequent experiments. Reiteration of this procedure eventually permitted selection of conditions and measurement of individual equilibria without strong interference from extraneous processes. Thus, a more accurate determination of many of the constants was possible than had been achieved previously. In some instances errors as great as 0.5 in pK were found for previously determined values.
An attempt was made to obtain experimental values not only for each of the independent constants, but for some of the redundant constants as well. This provided for independent check on the validity of some of the determinations.
One effect resulting from reactions 1-6 is a gradual increase of hypochlorite ion concentration with iocreasing pH. It appeared that one method of determining reliability of the equilibrium system was to compare computed values of OCl- concentrations with those found experimentally. Results of such a comparison are shown in Figure 14.9. Good agreement was attained.
