## Stabilizer
CYA Increase (ppm) = [Pounds of Stabilizer X 12] / (Pool Gallons / 10,000)
## Adding Stabilizer
Target CYA = Current FC / 0.075
## For Salt Pools
Target CYG (saltwater) = Current FC / 0.05
## Dry Acid to Muriatic
1 pound of Dry Acid = 26 fl oz of 31.45% Muriatic
1.25 pounds of Dry Acid = 1 quart (32oz) of Muriatic
5 pounds of Dry Acid = 1 Gallon of Muriatic
## Alkalinity Raising
Pounds of Sodium Bicarbonate (BP100) = [Desired TA Increase (ppm) * 1.4] / (Pool Gallons / 10,000)
## TA Lowering
## Total Alkalinity and Adjusted Alkalinity
Total Alkalinity is water's ability to resist pH changes. TA is the sum of all the concentrations of chemical ion species in your pool water that can react with (or consume) a hydrogen ion (H+).
Adjusted Alkalinity is the Total Alkalinity minus the CYA multiplied by Correction Factor, which is based on the pH.
However, since pools are usually between 7.2 and 8.2 pH, just use the following to get Adjusted Alkalinity:
AA = TA - (CYA * 0.33)
Basically, keep TA at around 80-120 during the winter, and 60-90 during the season
