Understanding Adjusted Alkalinity
A pool store printout shows "adjusted alkalinity", but presented as if it's the "real" alkalinity. It is only used for LSI and pH ceiling calculations, not acid dosing. Acid doses are based on TOTAL alkalinity, because cyanurate and borate contribute to the TA, and acid will neutralize on them too.
Show Notes
00:00] - Intro
[00:36] - Adjusted Alkalinity on a Pool Store Printout
[01:34] - Adjusted Alkalinity = Carbonate Alkalinity
[03:10] - Cyanurate and Borate also contribute to Total Alkalinity
[04:42] - Increasing CYA increases TA. About 1/3 of CYA is Cyanurate Alkalinity
[06:14] - Is Adjusted Alkalinity the "Real" Alkalinity?
[07:37] - One Breath Summary
