Most have heard of the Hamilton index and think it is nonsense as compared to the saturation index.
Since 1982 when I learned about it and used it never had any problems, with 175,000 service stops since then. With the exception of trying to keep the PH 8.0 to 8.2. I met Jock Hamilton at his chemistry class he was giving. Told all about his background. PhD in chemistry and at one time ran 300 service accounts. Then he said I will teach water chemistry in 20 seconds or less. My thoughts this guy is crazy just as you are thinking. Then he said throw away your phenol red you don't need it - even crazier! With my method you will never need the saturation test. Most of the techs were lost at that point. As well as me.
He stated 2 different water systems. One 2200 TDS the 1600 , hardness 600 400. Which one do you drain? The class agreed the TDS with 2200. His answer no the 1600 it has the calcium level of 600. He did state the 2000 TDS was work able due to the 400 calcium level. Both pools were on well water. So, he brought in water softeners to make the water correct. Know all the facts before making any adjustments.
Ok as you read this last line you will learn the Hamilton index. The harder the water the lower the alkalinity , simple as that sounds it works. I never checked the PH on a weekly basis, except commercial pools. Why add acid if the alkalinity is ok for the hardness - saves money and time. Check out the Index, it has changed since 1982 but very simple. Class anyone
