Chlorine helps keep a pool clean, and managing chlorine levels is an important aspect of owning a pool. Test your pool water daily if it gets regular use, and maintain a free available chlorine level between 1 and 3 ppm. For a circular pool, measure the diameter, divide it in half to find the radius, then use the formula πr The instructions will let you know how much to use to raise levels by 1 ppm per 10,000 gallons (38,000 L) of water.

Shock treatments bring free available chlorine levels to 8 to 10 ppm, which is outside of the safe range for swimming. Once you’ve measured and, if necessary, diluted the right amount of chemical, add it gradually to the pool. Simple floaters are inexpensive, while skimmers that clean debris and dispense chemicals can cost hundreds of dollars (U. They’re easier to use, last longer, and are gentler on pool liners than liquid options, which are best used as shock treatments. If your pool is circular, measure the diameter, divide that value by 2 to find the radius, then use the formula πr 2h, where r is the radius and h is the average depth.With over 20 years of experience in construction, Rob specializes in energy-efficient and drought-tolerant landscaping.
