Contact us

The best way to reach us is by email: hello@poolbalancecalc.com.

We especially welcome:

• Corrections: if a number, formula or claim looks wrong, tell us which page and why. We review every correction and update the page if needed.
• Calculator ideas: tell us what you were trying to work out and couldn't.
• Real-world results: if a dose moved your readings much more or less than a calculator predicted, the details (volume, readings before and after, product used) help us improve the assumptions.

We usually reply within a few days. We can't diagnose individual pools or give professional advice. For equipment problems or public pools, contact a pool professional or your local health department.
