How Much Pool Chlorine To Clear Up Swimming Pool Algae?
You know that smart people ask the right questions. So here’s the answer to that question: • Take the number of gallons in the pool and multiply by 8.34. This tells you how many pounds of water are in the pool. • Take the number 1,000,000 (a million) and divide it by the answer you have from your first calculation. This will tell you how many parts per million that 1 pound of chemicals will be present in your pool. • Take the number 10 and divide it by the answer you got after the second calculation. This tells you how many pounds of chlorine you will need to add to get 10 ppm. Example #1 Here’s an example with a 15,000-gallon pool: • 15,000 X 8.34 = 125,100. There are 125,100 pounds of water in a 15,000-gallon pool. • 1,000,000 divided by 125,100 = 8, well, close enough. This means each pound of chemicals added to the water will be 8 parts per million. • 10 divided by 8 equals 1.25, so you’ll need to add about 11/4 pounds of chlorine to get 10 ppm. Example #2 Here’s an 18,000-gallon p
