ADJUSTING THE TOTAL ALKALINITY IN THE POOL WATER . The method of adjustment is to determine the actual Total Alkalinity first by using a suitable test kit. For each ppm calcium carbonate by which the total alkalinity is less than 100 ppm, add 1.7 (or mg/L) pH BUFFER. Example: The actual total alkalinity was found to be 80 ppm.

Fluctuations in the pH levels can be minimised if correct alkalinity levels are maintained. The alkalinity is a measure of the ability of the water to resist changes in pH. The appropriate alkalinity level will depend upon the type of disinfection system used, and the material used to construct the water body.

Alkalinity protected fathead minnows against Cu toxicity in one study (Andrew, 1976) but did not alter Cu toxicity in another study (Erickson et al., 1996). Moreover, the toxicity of Cu2+ increased as alkalinity increased in the latter study, suggesting that Cu-carbonate complexes might be bioavailable.
