Our Story
We built mypoollab because we kept seeing the same thing: pool owners guessing.Dumping in salt because the water "looked off." Adding chlorine tablets by feel. Adjusting pH based on a forum post from 2014.
The information was out there, buried in threads, behind paywalls, or wrapped in so much complexity that most people gave up and called a pool service. Which is fine — until you're doing it yourself and you want an actual answer.
"Calculators existed. But they were scattered, ugly, and required an account for some reason."
So we made them free. No login. No subscription. Just your pool volume, your current levels,and the exact amount to add.
