1. General Information Only

The content, calculations, results, and information provided on this website are for general informational and educational purposes only. Nothing on this website constitutes professional advice of any kind. Results generated by this tool are estimates only and may not be accurate, complete, current, or applicable to your specific situation.

2. Calculation Sources & Authoritative References

The dosing calculations, chemical targets, and recommendations provided by this tool are derived from the following recognised industry and public health authorities:

• CDC Healthy Swimming Guidelines — Centers for Disease Control and Prevention. Free chlorine minimum 1 ppm (pools), 3 ppm (spas/hot tubs); pH 7.2–7.6; bromine 4–8 ppm spas. cdc.gov/healthywater/swimming
• NSPF Pool & Spa Operator Handbook — National Swimming Pool Foundation (the body that certifies pool professionals). Total alkalinity 80–120 ppm; shock targets 10 ppm standard, 20–30 ppm algae treatment; breakpoint chlorination at 10× combined chlorine.
• PHTA Technical Standards — Pool & Hot Tub Alliance (formerly APSP), the principal industry trade body. pH 7.2–7.6; CYA 30–50 ppm (chlorine pools), 60–80 ppm (salt pools).
• Taylor Technologies Dosing Factors — Taylor Technologies Inc., manufacturer of the K-2006 test kit used by pool professionals worldwide. Chemical dosing constants (e.g. calcium hypochlorite 65%: 0.154 lbs per 10,000 gal raises FC 1 ppm; sodium bicarbonate: 1.5 lbs per 10,000 gal raises TA ~10 ppm).
• Product Manufacturer Label Data — Dosing rates are cross-referenced against product packaging for calcium hypochlorite, sodium bicarbonate, cyanuric acid, muriatic acid, soda ash and other common pool chemicals.

These sources are used for reference only. Calculations are starting-point estimates and do not replace on-site testing, product label instructions, or advice from a licensed pool professional. Water chemistry is affected by many variables — including water temperature, cyanuric acid levels, bather load, sunlight exposure, and local water composition — that this calculator cannot account for. Always test your water before and after adding chemicals.

3. No Warranty — As Is

This website and all content, tools, calculators, and information are provided on an "as is" and "as available" basis without any representations, warranties, or guarantees of any kind, express or implied. We make no warranty that the tool will be error-free, uninterrupted, or that results will be accurate or fit for any particular purpose.

4. Limitation of Liability

To the fullest extent permitted by applicable law, the owners and operators of this website shall not be liable for any direct, indirect, incidental, special, consequential, or punitive damages arising out of or in connection with your use of this website, including but not limited to: personal injury or death, property damage, chemical injury, or financial loss. Your use of this website is solely at your own risk.

5. Verify All Results Independently

Always cross-check results with official manufacturer documentation, product labels, industry standards, or qualified experts before taking any action. Calculations are provided as a starting point only. The tool does not account for local regulations, water temperature, cyanuric acid levels, bather load, or individual circumstances.

6. Health and Safety Warning

Pool chemicals are hazardous substances that can cause serious injury if handled incorrectly. Always follow manufacturer instructions and safety data sheets (SDS) for every chemical product. Never mix pool chemicals together. Always add chemicals to water, never water to chemicals. Wear appropriate protective equipment. Keep chemicals away from children. When in doubt, consult a licensed pool professional.
