Pool School Episode 2 | Pool Water Testing: Alkalinity, pH, and Chlorine (Part 1 of 3) Learn basic water chemistry and how to test your swimming pool water for alkalinity, pH, and chlorine in this comprehensive guide from Mike the Pool Guy! Great for any kind of swimming pool: in-ground, above-ground, half-ground (semi-inground). This video is part 1 of a 3-part series on pool water testing and will cover the basics of these three important chemical levels. In this video, you will learn: Why it's important to test your pool water for alkalinity, pH, and chlorine How to use test strips to accurately test your water The ideal ranges for alkalinity, pH, and chlorine What can happen if these levels are too high or too low How to adjust alkalinity and pH levels This video is perfect for anyone who wants to learn how to keep their pool water clean and safe! Subscribe to our channel for the next video in the series, where we will discuss sterilization and the different types of chlorine. Swimming Pool Maintenance: The Basics 1. Total Alkalinity is a measure of the total number of Alkali ions in the water. If the Alkalinity is too low, small changes in the acidity of the water will cause large swings in the pH, making it difficult to keep the pH balanced. High Alkalinity will cause the water to resist pH changes. a. Low Alkalinity-Add baking soda. 1 lb will raise 10,000 gal. ppm. b. High Alkalinity-Add water. Usually adding 2-3 inches of tap water is enough. 2. pH is a measure of the acidity of the water. This is important to balance for two reasons. First, if the pH is not balanced, the chlorine and other chemicals break down and are useless. Second, if the pH is not balanced, the acidity of the water will cause swimmers' eyes to become red and irritated. Because the pH of your eyes is only 7.2, anything higher may cause irritation. a. Low pH-Add pH Plus (Soda Ash). 1 lb will raise 10,000 gal. 0.2 on the test strip. b. High pH-Add ph Minus (Acid). 1 lb will lower 10,000 gal. 0.2 on the test strip. 3. Shock is an oxidizing agent that reactivates the chlorine in the water, and helps burn out other contaminants in the water. Normally, it is necessary to shock the pool once a week no matter what type of chemical maintenance program you are using. There are many types and brands of shock available. The recommended type will have potassium monopersulfate as the active ingredient, regardless of the brand. Use 1 lb per 10,000 gal. every week. 4. Whenever adding chemicals, make sure the filter is running, and slowly pour the chemicals into the skimmer. Allow 2 hours before re-testing the water. Putting chemicals directly into the pool can bleach the liner. 5. Conditioner is a water treatment that helps prevent chlorine loss due to sunlight. It is a once or a twice a year treatment. The first year add 3 lbs. Every year after that, have your water professionally tested to determine how much to add. If a lot of make-up water has been added, it may be necessary to add more conditioner during mid-season. Have the water professionally tested to determine the proper amount. When adding conditioner, dissolve it in hot water first and slowly pour it into the skimmer. It can also be poured into an old stocking, which is tied off, and then put into the skimmer to dissolve.
