"We love your advice on how to cut cost of using alternative chemicals as opposed to having to buy what the pool store offers, such as using baking soda instead of alkalinity plus. It has not even been 24 hours and our pool looks amazing!"

Your pool should be a source of joy, not stress. In less than 60 seconds, you'll get a custom treatment plan based on your actual water test results. And you won’t be sold a bunch of chemicals.
Use any pool test strips, drops, or a digital reader you already own.
Just slide each chemical reading into place or type in the numbers. Test for basics like chlorine and pH, or get detailed with alkalinity, stabilizer, salt, and calcium hardness.
Skip the confusing pool store advice and math calculations. We'll tell you exactly which chemicals to add and precisely how much based on your pool's actual size. No more buying unnecessary chemicals or second-guessing amounts.
Tap each step as you finish it so you always know what's done and what's left. Then put the phone down and use the pool.
Inside the app, you'll get instant access to on-demand pool education and real-time chat support. Whether you're cleaning your filter, shocking your pool, or dealing with algae, you'll see exactly what to do from pool pros.
Try it free for 7 days! After that, it's just $49.99 a year. Credit card required. Cancel anytime.
