Hey Product Hunt! 👋

I'm Polash, the maker behind MyPoolLab.
I built MyPoolLab after noticing how unnecessarily difficult basic pool-chemistry calculations can be.


If you own a pool, you've probably asked questions like:

  • How much salt do I need?

  • How much chlorine should I add?

  • How much shock should I use?

The formulas aren't necessarily complicated, but finding the right calculation, understanding the units, and converting the result into something practical can be frustrating.

So I started building MyPoolLab — a collection of simple, free calculators that turn those calculations into clear answers.

The goal is to make pool maintenance a little less intimidating for beginners while still being useful for experienced pool owners and professionals.

We're starting with the core calculations and plan to keep expanding the toolkit.

I'd really appreciate your feedback:

What pool chemistry calculator would you want me to build next?

And if you find something that's confusing or inaccurate, please tell me. I'd much rather know about it and improve it. 🙏

Thanks for checking out MyPoolLab!
