1. Estimates, not measurements
The calculators on PoolCareCalc produce estimates from standard, published pool-chemistry formulas. Your pool’s actual chemistry depends on many factors we can’t see. Always test your water with a reliable kit or strips, add chemicals gradually, and re-test before relying on a result. We make no warranty as to the accuracy or suitability of any figure.
2. Pool chemical safety
Pool chemicals can be dangerous if mishandled. Never mix different chlorine products, and never mix chlorine with acid — doing so can release toxic gas. Always add chemical to water, never water to chemical, and follow the manufacturer’s label and safety instructions. Store chemicals separately, away from children and pets. If in doubt, consult a licensed pool professional.
3. Not professional advice
PoolCareCalc is an independent informational website. Nothing here is professional, medical, or engineering advice, and we are not affiliated with any manufacturer or brand mentioned. For equipment selection, plumbing, or persistent water-quality problems, consult a qualified pool professional.
4. Product data & cross-reference
Filter-cartridge model numbers, sizes, and Pleatco / Unicel / Filbur equivalents are compiled from published manufacturer and aftermarket charts and are provided for reference. Dimensions are nominal and can vary between brands — always confirm against your existing cartridge before purchasing.
5. Affiliate & advertising disclosure
PoolCareCalc contains affiliate links, including links through the Amazon Associates program. As an Amazon Associate we earn from qualifying purchases. We may also display ads through third-party networks such as Google AdSense. Affiliate relationships never change our calculator results or cross-reference data. See our privacy policy for how ad and analytics data is handled.
6. External links
We link to third-party sites (such as retailers and manufacturers). We don’t control and aren’t responsible for their content or practices.
