Things you’ll be testing for include chlorine, PH, total alkalinity, Cyanuric acid (stabilizer), and calcium hardness. The levels need to be properly balanced for safe and clean water before swimming in it. The free chlorine level should be between 2.0 and 4.0 ppm. The PH level should be between 7.2 and 7.8.
Likewise, people ask, how soon after filling a pool Can you swim?
Chlorine/non-chlorine chemicals – When adding chlorine or non-chlorine chemicals to “shock” your pool after a fill-up, wait about 24 hours or until levels are approximately 5 ppm. If you’ll only be adding liquid chlorine, it’s generally safe to swim after about 4 hours or until levels are 5 ppm or lower.
Simply so, how often should you change the water in an above ground pool?
Generally, pool water needs to be replaced once every five to seven years. This should be done during mild weather so that your pool surface is not at risk from strong sunlight and heat. Your pool maintenance company can recommend when it is time to drain your pool.
