My first tests since having the plaster replaced. I tested the pH which not surprisingly was below 6.8 (base demand was 17) since I added 6 gallons of muriatic acid per instructions for an acid startup because of the 3M Colorquartz Crystals. Next I tested Total Alkalinity at 40, and Calcium Hardness at 290. To start to balance the water I added 4 lbs. of Baking Soda (approx. 1/2 of amount needed according to treatment chart included in my test kit (Leslie's #18-576) made by Taylor. Since I have not yet added any Cyanuric acid or Chlorine there was no need to test for them.
After bringing up the TA, I will raise the pH, then add the conditioner, a metal sequestering agent and chlorine. Over the past 4 years of taking care of this pool I don't think that I have brushed it as much as I have in prepping the new plaster. According to the salesman who recommended the Quartz Chrystals I should wait for about a month before putting in the Hayward Ultra Vac or a solar cover.
Does waiting a month sound too long?
