Low salt - ppm dropped after adding

So my system is showing "low salt" error. It was at 2650pp. yesterday, I added 60lbs and waited. Now it's at 2600ppm. I added the other 20lbs from the leftover last night.

It still says 2600ppm.
I just turned on the SWG about 30 minutes ago.
What am I supposed to do now?

If you are using the display on the swg to determine the salt level, that may not be accurate. Most here agree the taylor k1766 is the most accurate way to test salt levels. A disagreement between the actual and reported levels on the swg display could indicate swg sensor or cell degradation.

You should test the salt level with the Taylor K1766. Once you know that level, you can look through the SWG manual on how to recalibrate your SWG. I did that earlier this pool season. So far the salt water readings on the SWG are agreeing with my test results.
