I never venture to the pool store aside from needing a part or two. I have been recently having problems with my salt power supply and wanted to get a salinity reading so I took the local store some water to test.
All numbers came back as I expected more or less (as verified by my TF-100). But one value of theirs stood out.
They had something called Alkalinity (w/stabilizer correction) listed as 23ppm with suggested value of 100-180ppm. I know my TA as measured myself was 70, so I am not entirely sure of what they were measuring. I do know they suggested 34 lbs 11.9 oz of Alkalinity Plus which I politely declined.
Since I never have these guys test my water, is this some sort of new measurement, and does it really mean anything?
