Why Is Proper Water Chemistry So Important?
Pool water chemistry is the most vital yet misunderstood component to overall pool care. Proper water chemistry protects not only swimmers but also the swimming pool itself. Heaters, filters, vinyl liners, and even plaster can all suffer severe damage from improperly balanced pool water. Four key components of swimming pool water chemistry are….
Total Hardness refers to the amount of calcium and magnesium in your water. Depending on your pool surface, hardness should measure 175 – 275 ppm. When total hardness is too high, scale forms causing the water to appear cloudy. When total hardness is too low, the water will corrode metal fixtures (including copper heater components), reducing heater effectiveness by as much as 75%.
Chlorine is a disinfectant designed to sanitize and oxidize contaminants in your pool water. To be optimally effective, chlorine must be continually active so that it can react instantaneously with bacteria, algae and other organic matter as they are introduced into the water. The level of active chlorine is called “free chlorine” and should measure 1.0 – 3.0 ppm.
Total Alkalinity measures the amount of alkaline substances in the pool water. When total alkalinity is too low, the water will corrode metal fixtures. Low alkalinity can also cause staining and weaken vinyl liners causing wrinkles.
PH refers to the intensity of acid or alkaline materials in your pool water. pH is measured on a pH scale from 1 (extremely acidic, like lemon juice) to 14 (extremely alkaline). A pH of 7.0 is considered neutral, but ideal pool water pH should measure 7.4 – 7.6. pH higher than 7.8 can cause skin irritation and red eyes. High pH will also reduce the effectiveness of chlorine and cause the water to appear cloudy. Low pH, or pH less than 7.2, causes eye and skin irritation and corrodes metal fixtures, especially copper heater components.
