Editorial policy
Pool Care Calculators publishes calculator-first pages. The editorial goal is not to sound authoritative by using bigger words. The goal is to make the math visible, name the assumptions, and keep users from treating an estimate as a perfect lab result.
A page is only useful if it answers a concrete pool owner question: how many gallons, how much salt, how much chlorine, how much stabilizer, or how to stage a pH or alkalinity adjustment. Generic pool articles are not the core product.
When a result comes from a clear formula, the page shows the formula or the dosing relationship. When a result uses a conservative estimate or simplified assumption, the page says so.
Pool chemicals can damage surfaces, equipment, clothing, and skin when handled badly. Safety notes are written directly: follow labels, avoid mixing chemicals, add in stages, circulate, and retest.
Formulas, assumptions, and source notes are shown near the calculator experience. The calculators are independent estimates for routine maintenance planning, not manufacturer approval or a licensed pool-service diagnosis.
Pages are reviewed when a formula changes, a new calculator is added, a source link breaks, or manufacturer guidance suggests a target range or assumption should be revised.
If affiliate links or sponsored placements are added later, they should be labeled near the link. Commercial placement should not change the calculator formula or safety guidance.
If a formula or source is wrong, the correct fix is to update the calculator, the explanation, and the related tests together. A quiet copy change is not enough when the math changes.
Some pool conditions need more than a calculator: algae, combined chlorine problems, cloudy water, metal staining, plaster startup, commercial pools, and suspected contamination. In those cases, use a qualified local professional and the relevant product documentation.
