Calculator estimates are not professional advice
Pool Care Calculators provides estimates based on user-entered values and published formulas. The results are planning tools, not prescriptions. Always verify any dose against product label directions, equipment manufacturer specifications, and local health and safety requirements.
Pool chemicals can be dangerous if misused. Follow all safety precautions on the product label, including protective equipment, handling instructions, and storage requirements. Never mix chlorine products, and never add water to acid.
No professional relationship
Using Pool Care Calculators does not create a professional-client, consultant, or service provider relationship. The site does not provide certified pool operator advice, engineering judgments, or water-quality diagnostics. If you are unsure about a chemical addition, consult a certified pool professional or your local health department.
No liability for chemical use or water quality
Pool Care Calculators, its operators, and contributors are not liable for any damage, injury, or loss resulting from the use of the calculators, the information on this site, or the application of any chemical dose, pool equipment adjustment, or water treatment decision made based on these estimates.
Pool owners are responsible for their own water testing, chemical handling, equipment operation, and compliance with local regulations.
Affiliate links and commercial relationships
Some pages may contain affiliate links. If a link is an affiliate link, it will be labeled near the link. Affiliate relationships do not change calculator formulas, source references, or safety guidance. Product recommendations are not endorsements and should be verified against independent reviews and product documentation.
Changes to these terms
These terms may be updated when the site changes or when legal guidance recommends clarification. Continued use of the site after updates means the new terms apply.
