For some reason I couldn’t get control of my pool. Been pretty good at it for the last 10 years. Thought it could be my Taylor kit being out of date but apparently Leslie’s kits often are they said. Really this is the only time I looked at the expiration dates so I wouldn’t know. Anyways I thought I’d try getting test from two different pool supply stores here next to me and compare them to my readings. 3 very different results. A-is me. B-store one. C-store two. Store two now uses an electronic type not a drop test.
FC and TC, ABC all agrees High
PH, A-7.4, B-7.8, C-8.3
TA, A-90, B-110, C-61 (adjusted because of high CyA)
CyA, A-not tested, B-100, C-106
So I always try to get my TA right first then PH. My test is on the low side but considered ok. Store B wants it down and store C wants it up. They both want PH down. But it’s not good habit to mess with PH until TA is good. Which should I believe. Mine, store one or store two. Uggh.
