How This Calculator Works
- Chlorine dosing: Based on the active chlorine percentage of the product. Liquid chlorine (sodium hypochlorite) is typically 10% available chlorine. Dichlor is 56%. Trichlor is 90%. Cal-hypo is 65%. The calculator adjusts the amount based on which product you use.
- pH adjustment: Muriatic acid (31.45% hydrochloric acid) lowers pH. Soda ash (sodium carbonate) raises pH. Amounts are calculated per 10,000 gallons and scaled to your pool size.
- Alkalinity: Baking soda (sodium bicarbonate) raises alkalinity with minimal pH impact. 1.5 lbs per 10,000 gallons raises TA by approximately 10 ppm.
- Cyanuric acid: Stabilizer protects chlorine from UV degradation. 13 oz per 10,000 gallons raises CYA by approximately 10 ppm. Dissolve in warm water first since it's slow to dissolve.
