What can this be? What am I missing? I had cleaned the internals of the SWG it was ok at 3200-3400 but it dropped like 200 last few days. Am I missing something? Chlorine levels and clacium and CYA are around optimal.
200 is probably within the error ratio of your tests.
That said, there is only one thing that will cause a quick drop in salt levels - water replacement. So, have you had heavy rains that have caused you to need to drain, or do you have an auto-fill? Or heavy backwashing?
