Reference charts
Use these charts for quick planning, then open the matching calculator when your pool size, product strength, or test reading differs from the common examples.
Salt reference
Use this pool salt chart to estimate pounds of salt for common swimming pool sizes and ppm increases. It uses the same gallons x ppm x 0.00000834 formula as the pool salt calculator.
Chlorine reference
Use this chlorine dosing chart to estimate gallons of 10% liquid chlorine for common pool sizes and free chlorine ppm increases. It is a planning chart, not a product label replacement.
CYA reference
Use this FC/CYA chart as planning context for how cyanuric acid changes free chlorine targets. It supports the chlorine, stabilizer, and shock calculators.
Volume reference
Use this pool volume chart to estimate gallons for common round and rectangular pools. It uses cubic feet x 7.48 gallons and should be checked with the volume calculator for custom shapes.
Quality rule
Pool chemical numbers are only useful when the assumptions are visible. Each reference page shows how values are calculated, which calculator to use next, and when product labels or equipment manuals override a quick chart.
Best workflow
The chart gives a common-value baseline. The calculator adapts that baseline to your actual readings. Retesting after circulation tells you whether the pool responded as expected.
