Professional-use disclosure

Screening outputs, not approvals

Calculator results, reference values, guides, and Workspace reports are provided for informational screening. They are not professional pool-service advice, not a code compliance determination, not a contractor quote, and not a promise of savings or performance.

Code and authority having jurisdiction come first

Where this site discusses dosing, equipment sizing, or pool practice, product labels, manufacturer instructions, and locally adopted pool codes always govern. If a calculator result and a product label disagree, the label wins. Chemical handling and equipment work should follow label directions and local law.

Rates and tariffs must be verified

• Confirm current utility rates: electric rate, gas price, water and sewer rates, demand charges, ratchet clauses, and riders.
• Confirm test-kit history: recent chlorine, pH, alkalinity, and CYA readings, not a single old strip.
• Confirm equipment facts: heater BTU and efficiency, pump watts and GPM, filter size, and salt-cell model specifications for EVs.

No conflicts, no paid placement

Calculator defaults and guide examples are editorial choices, not endorsements. The site does not accept payment to favor equipment, installers, lenders, or rate plans in its tools or content. If that ever changes for a specific page, the relationship will be stated on that page.
