(chart found at http://www.whitmer.com/saturation_index.htm). This system takes into account pH, alkalinity, water temperature, chlorine and calcium hardness. We recommend that for the first 30 days pH and alkalinity be monitored regularly as they can directly affect the appearance of the surface. It might help to maintain levels of pH, alkalinity and calcium hardness toward the lower end of the index. Keep in mind, based on your water source, you may need to add “Muriatic acid” to your new pool 2 to 3 times per week during the first month.After 30 days, the pool should be checked 1 to 2 times per week and adjusted accordingly. If your finish is a darker colour, in particular black, it is even more important that you follow these instructions. Do not chlorinate your pool until water is filtered and pH and alkalinity are acceptable. Chlorine is highly reactive and can cause metals or minerals to precipitate (cloud water, scale and/or stain). A number of pool supply retail stores have computerized testing equipment to help you monitor these factors as well as others (cyanuric acid, metals, etc.).
pH 7.4 – 7.6
Total Alkalinity 80-120ppm
Calcium Hardness 200 – 400ppm
