Salt Test Reading

[Steve-D]

Maybe a dumb question, but in reading the K-1766 salt test do you stop counting at the first flash of pink/salmon even if it goes back to yellow or do you stop at a solid salmon color? I knew my salt was high from the IC40 reading and the fact that I can taste it quite strongly, but my readings are inconsistent and I'm not sure if its because of possibly not exactly hitting the 10 ml mark or maybe an oops with the dropper that I didn't catch or if I'm just not reading the results correctly. Today's reading is higher than Sunday's reading and I don't know what to make of that.

ScreenLogic's monitoring puts Salt at 4600 ppm which I matched when testing on Sunday. Today I got a reading of 5000 but saw the first flash of red/salmon at 23 drops which would have been 4600. According to the instructions "First change from yellow to a milky salmon (brick red) is the endpoint," but is that at the flash of the color change or when the color change is stable?

[edit] This is a brand new pool filled by truck in early May and the installers clearly dropped maybe 4 bags too many of salt. I only got my test kit this weekend to get specific numbers but the Intellichlor SWG had been flashing "high salt" from when it was first turned on.

do you stop at a solid salmon color?

^^This. Solid salmon/brick color. Don't worry too much about the K-1766 not matching the SWG reading. They almost never match as the SWG sensors can fluctuate. I often find about a ~400 variation between the two.

It has to stay the brick red color.

Thank you both @Texas Splash & @PoolGate. I wasn't concerned so much with not matching the system reading as with the fact that my own readings were so different between Sunday and this morning and I'm trying to understand why so that I can be more consistent and (hopefully) get more accurate readings going forward.

Also keep in mind the tests are accurate to within +/- 400 parts.
