About
Kestrel Analytics Inc. operates Saltwater Pool Calculator from 401 East Las Olas Boulevard, Suite 1300, Fort Lauderdale, FL 33301, United States.
The job it does
Salt pool owners learn the right amount of salt to pour in, the amount of water to change if salt gets too high and the way to check and look after a salt cell. All the tools run right in your browser and whatever you enter stays on your device.
The source of each number
The chlorinator brands' own manuals supply the targets, limits and light codes: Hayward, Pentair, Jandy, CircuPool, Intex and Bestway. The manual behind each tool is linked on its page. Published retailer listings supply the figures, and each one is labeled as a list price.
The small print
What you get here is plain pool-chemistry math. For your equipment and its warranty, the manual that came with your chlorinator is the last word.
