High Calcium Hardness (CH) Advice
Below is an example of a CH advice message you may receive after your TEST results are analyzed:
"Your measured calcium hardness (CH) is %CHmeas and is too high. Dilute/replace %drain gallons of pool water".
High CH can precipitate scale. Keep CH at the appropriate level for balanced pool water.
Below is an example of a Target CH advice message you may receive after your TEST results are analyzed:
"Your Target CH is %CHtarg"
- Target CH level is dependent on your pH, total alkalinity (TA), cyanuric acid (CYA) levels and on water temperature.
- CH rises from evaporation and refill with high hardness water or from use of Cal-Hypo chlorine.
