About mypool.tools

Pool chemistry shouldn't require a chemistry degree. But somehow, every pool calculator on the internet is either buried in ads, locked behind a paywall, or asks you to create an account before telling you how much chlorine to add.

We built mypool.tools because we wanted better tools for ourselves — and figured other pool owners did too.

What we believe

Calculators should just work. Enter your numbers, get your answer. No account required. No email capture before seeing results. No app to download.

Information should be honest. We cite our formula sources (CDC, EPA, APSP/PHTA). We tell you when a calculator gives an estimate vs. an exact answer. We don't recommend products we wouldn't use ourselves.

Design matters. Pool tools don't have to look like they were built in 2008. We put real effort into making these tools clear, fast, and pleasant to use — on any device.

How we make money
