Went to the pool store. The container I had the pool water in fell over on its side and leaked, so I didn't have enough for a complete test.

What I did test:
Salt = 3900
FAC = 0
TAC = 0
pH = 8

Came home, still indicates 1600. Turned it to Super Chlorinate and 100% since I have no chlorine, and it said it was generating. Went over and turned the water on to fill the pool (it was low and I obviously need to dilute)--came back and it was no longer generating, but the indicator had changed to 2200.

Why do these units read inaccurately when the salinity is high? I saw another post on here about a guy who's reading was 0 or 400, and when he got it tested it was like 4000.
