5,000 gallon pool chemical doses
Chemical doses for a 5,000 gallon pool: chlorine, muriatic acid, baking soda, soda ash, calcium, CYA and salt, in one table for the route.
| To do this | Add about |
|---|---|
| Raise free chlorine 1 ppm | 5.1 fl oz liquid (12.5%), or 1.0 oz cal hypo (65%) |
| Raise free chlorine 3 ppm | 15 fl oz liquid, or 3.0 oz cal hypo |
| Lower alkalinity 10 ppm | 13 fl oz muriatic acid (31.45%) |
| Lower pH about 0.2 from 7.8 | 6.0 fl oz to 8.0 fl oz muriatic acid, depending on alkalinity |
| Raise alkalinity 10 ppm | 0.7 lb baking soda |
| Raise pH about 0.2 | 3.0 oz soda ash |
| Raise calcium 10 ppm | 0.6 lb calcium chloride (77%) |
| Raise CYA 10 ppm | 6.5 oz cyanuric acid |
| Raise salt 100 ppm | 4.2 lb pool salt |
These are estimates from commonly used dosing figures. Products vary, so follow the label and SDS, add chemical to water, never mix chemicals, and test again after circulating. Local code may set different ranges.
Common questions
How much liquid chlorine does a 5,000 gallon pool need to raise 1 ppm?
About 5.1 fl oz of 12.5% liquid chlorine.
How much muriatic acid lowers alkalinity 10 ppm in 5,000 gallons?
About 13 fl oz of 31.45% muriatic acid. It also lowers pH, so retest after circulating.
