POOL MAINTENANCE & CHEMICAL DEFINITIONS
Preferred Water Chemistry Reading
| Minimum | Ideal | Maximum |
| Copper Ions | 0 | 0.1 - 0.2 ppm | 0.2 ppm |
| Free Chlorine | 0 | 0.4 - 1.5 ppm | 3.0 ppm |
| Combined Chlorine | 0 | 0 ppm | 0.2 ppm |
pH | 7.2 | 7.4 - 7.6 | 7.8 |
| Total Alkalinity | 100 ppm | 100 - 140 ppm | 140 ppm |
| Calcium Hardness | 150 ppm | 200 - 400 ppm | 500 - 1000 ppm |
| Stabilizer (Cyanuric Acid) | 10 ppm | 30 - 50 ppm | 100 ppm |

|
|
Free Chlorine - | Is the chlorine residual present in pool water. | ||
|
|
|
|
Combined Chlorine - | Is formed by the reaction of free chlorine with ammonia | ||
| wastes. |
|
|
| Result if too high - Sharp chlorinous odor, eye irritation. | ||
|
|
|
|
pH - | A value that indicates how acidic or basic a solution is. | ||
| Result if too low - Corroded metals, eye & skin irritation, | ||
|
| destruction of total alkalinity. | |
| Result if too high - Scale formation, cloudy water, shorter | ||
|
| filter runs, eye & skin irritation, poor | |
|
| chlorine efficiency. |
|
|
|
|
|
Total Alkalinity - | Indicates the degree of the water's resistance to change | ||
| in pH. It determines the speed and ease of pH change, | ||
| so always adjust total alkalinity before adjusting the pH | ||
| level. |
|
|
| Result if too low - Corroded metals, eye & skin irritation. | ||
|
| Low alkalinity will cause the pH to be | |
|
| unstable. Any chemical added to the | |
|
| water will have an affect on pH. | |
| Result if too high - Scale formation, cloudy water, | ||
|
| eye & skin irritation, poor chlorine | |
|
| efficiency. |
|
|
|
|
|
Calcium Hardness - | Refers to the amount of calcium and magnesium | ||
| dissolved in the water. |
| |
| Result if too high - Scale will form and will cause the | ||
|
| water to become cloudy. | |
|
|
|
|
Stabilizer - | Stabilizers extend the life of chlorine in swimming pools. | ||
(Cyanuric Acid) |

•Do not add pool chemicals directly to the skimmer. This may damage the cell.
•Maintaining a salt and sanitizer level above the recommended range can contribute to the corrosion of the pool equipment.
•Check the expiry date of the test kit as the test results may be inaccurate if the kit is used after that date.
•If, due to heavy pool usage, it is required to increase the sanitizer level, then use a chemical based on
