How to Use This Calculator
- Enter your water volume (gallons or liters) and set target calcium, sulfate, and chloride levels (ppm).
- Enter your source water calcium level so the calculator adjusts additions accordingly.
- Review Gypsum (g) and Calcium Chloride (g) additions needed.
- Check Resulting Calcium and Sulfate-to-Chloride Ratio to confirm your target water profile.
