A Theory About Rising pH in SWG Pools

[PatL34]

Kurt,

As I am still curing my Diamond Brite plaster, my last CH reading was 270 ppm.

I filled the pool entirely with softened water, to help the curing, and tried as much as I could to keep the pH to between 7.2 - 7.6 using roughly a pint of acid a day.

During the first month I kept the SWCG off line, and used trichlor and bleach to maintain about 5 - 7 ppm Cl. Once I got to about 90 ppm CYA, I started using bleach only. I have not added any baking soda, letting the TA build up of its own accord.

As of now The PoolPilot SWCG is on at a power level of 1 and 50% output. So far no hint of algae, and I can only ascribe this to the plasterer who really knew what he was doing, and to what I am doing.

I will be taking a full set of figures today, and let you know what I have.
