The $2 Trick That Makes Your Pool Chlorine Last Longer in Summer

Pool won't hold chlorine past mid-afternoon? Test it tonight after sunset and again at sunrise, and that one free test tells you what's really eating it. Without stabilizer, direct summer sun can wipe out nearly all your chlorine in about four hours. The fix costs a couple bucks a pound, but used wrong, it's the same stuff behind the green pools I get called out to every August. In this video I walk you through the overnight chlorine loss test and what a pass or a fail means, why refilled pools, liquid chlorine pools and salt water pools start the summer with zero stabilizer, what plain cyanuric acid really costs, how much a 20,000-gallon pool needs, and how to add it with a sock at the return jet so it doesn't etch your plaster or wrinkle a vinyl liner. Over 20 years of fixing backyard pools, passed along to you.
