Corrections
Formula changes should be visible, testable, and sourced.
Pool chemistry content has to be handled carefully. A typo in a formula, unit, product strength, or source note can change what a pool owner adds to the water. Corrections are treated as product fixes, not casual copy edits.
What gets corrected
- Wrong formula constants, unit conversions, or product-strength assumptions.
- Calculator bugs that change the result or hide an important warning.
- Broken source links or source notes that no longer support the page.
- Unsafe wording that could encourage mixing chemicals, overdosing, or skipping retesting.
How fixes are handled
- Reproduce the issue with the exact calculator inputs or source URL.
- Check the formula or wording against a public source, product label, or manufacturer document.
- Update the calculator, explanation, source note, and tests together when the math changes.
- Update the last-reviewed date when a formula or source record changes.
Current limitation
Pool Care Calculators does not currently publish a full public changelog for every wording adjustment. Formula and source governance is tracked in the site source data and test suite. A public changelog is planned before the calculator library expands into a larger programmatic SEO system.
