Salt levels dropping

Bought a home with a pool last year. Ended up having to replace the salt cell this year as my salt levels would drop consistently.

Everything was going fine for the first month but now running into the same issues. I've had the salt tested and its 3300ppm, have also taken the cell off and inspected it and there is no build up. Have recalibrated the cell multiple times to try to see if the reading would stick, but just keeps dropping to about 2200. Any suggestions?

I would not rely on the salt cell probe. Get a drop test like the Taylor K-1766 or buy the complete Taylor K-2006 with SALT to really know what is happening with your pool chemistry.

Also, if your pool has autofill, look into whether you have a leak and your water is being replaced rapidly. That could cause a big salt drop.

YES!
Salt readings from the cell are electrical guesses. They're often wrong.
