Pool water analysis parameters

Free chlorine

• One of the most commonly used components for swimming pool water treatment.
• The free chlorine value ladder: 0,0.5,1,3,5,10 ppm
• Optimal value between 1 and 3 ppm
• <1 we will use chlorine in tablets or granules or if the level is very low we will carry out a shock chlorination.
• >3 increase the hours of filtration or use a chlorine or bromine neutralizer. 

pH

• It is the level of acidity in the water and the first parameter to analyze.
• The ladder of pH values: 6.2,6.8,7.2,7.8,8.4
• Optimum value between 7.2-7.6
• If less than 7.2 use pH increaser.
• If higher than 7.6 use pH reducer.

Alkalinity

• Indicates the ability of the water to neutralize acids and stabilize the pH.
• The alkalinity value ladder: 0,40,80,120,180,240 ppm
• Optimal value between 120 and 150 ppm
• Below 100 ppm is considered low alkalinity and we will use alkalinity increaser.
• Above 175 ppm is high alkalinity and pH reducer will be used.

Cyanuric acid

• A stabilizer of chlorine that increases its permanence against solar radiation.
• The cyanuric acid value ladder: 0, 30,50,50,100,150,300 ppm
• The level cannot exceed 75 ppm
• If this level is exceeded, the water must be renewed.

Advice for use

• Keep the tube tightly closed to prevent humidity from entering. 
• Avoid picking up the strips with wet or damp hands. 
• Store in a cool, dry place. 
• Do not use after the date printed on the tube.
