1. Mastering Pool Water Chemistry

The foundation of a healthy pool is balanced water chemistry. Imbalanced water can be uncomfortable for swimmers, corrosive to equipment, and ineffective at sanitizing. Regular testing and adjustment are non-negotiable.
1.1. Regular Testing is Crucial
Test your pool water at least twice per week during peak season, and once a week during milder weather. Use a reliable test kit or test strips. The core parameters to monitor are: Free Chlorine, pH, Total Alkalinity, and Calcium Hardness. Cyanuric Acid (stabilizer) levels should also be checked periodically.
1.2. The Pillars of Balance: pH, Alkalinity, and Hardness
These three factors are interconnected. Total Alkalinity (TA) acts as a buffer for your pH; aim for 80-120 ppm. Correct TA first, as it makes pH easier to manage. pH measures how acidic or basic your water is; the ideal range is 7.4 to 7.6. Low pH corrodes equipment and irritates eyes, while high pH causes scaling and reduces sanitizer effectiveness. Calcium Hardness prevents water from becoming corrosive or scaling; maintain between 200-400 ppm for plaster pools and 175-225 ppm for vinyl liner pools.
1.3. Sanitization: Keeping Germs at Bay
Sanitizers, primarily chlorine or bromine, destroy harmful bacteria and contaminants. Maintain Free Chlorine between 1-3 ppm. Shock treatment (super-chlorination) is necessary weekly or after heavy use to destroy combined chloramines, which cause odor and eye irritation. Ensure your Cyanuric Acid (stabilizer) level is between 30-50 ppm to protect chlorine from rapid sun degradation.
