Chemical Safety & Operational Disclaimer
Effective Date: October 2026
1. Never Mix Chemicals Together
NEVER mix any chemicals together before adding them to your swimming pool water. In particular, NEVER mix acid (such as muriatic acid or dry sodium bisulfate) with chlorine. Combining acid with chlorine immediately produces lethal toxic chlorine gas (Cl2).
2. Add Chemical to Water, Never Water to Chemical
When diluting chemicals in a bucket (such as calcium chloride or dry acid), always fill the bucket with cold water first, then slowly add the dry chemical. Adding water directly onto concentrated dry chemicals can generate violent boiling splatters.
3. Accuracy of Calculations
The calculations provided by MyPoolLab are mathematical approximations based on typical chemical purity and standardized water temperatures. Factors such as high bather load, sunlight intensity, wind evaporation, and tap water mineral variation can alter results. Always test your water with a calibrated test kit before and after adding chemical additions.
