The last time we met, we discussed pH (THE RULER). You learned that this component of water chemistry is important because it has a direct effect on swimmer comfort and chlorine activity. The pH of your water is crucial in providing a pleasant pool experience, however, from time to time it tends to be a bit moody. Changes to the environment, such as an increase in swimmers, rain, organics, other chemicals, or anything else that may enter the pool can trigger the pH to fluctuate.
This is where Alkalinity (THE SOOTHER) comes into play. Alkalinity is like a shock absorber for pH’s mood swings. It keeps pH more stable and helps to prevent radical changes. Alkalinity says, “Hey, pH there is no need to go to 8 or 6, why don’t you just hang out here with me in the 7 range and relax”. By keeping your alkalinity in the 80-120 ppm (parts per million) you can keep the pH from drifting. In doing so you create a better and safer swimming environment. Enjoy your pool!
Ricks Rule of Thumb:
1.5 pounds of alkalinity raises alkalinity 10 ppm in 10,000 gallons.
