Is this a fresh fill of water? You said the cell was caked with calcium in the first post. It has to operate for that happen. Help us out with a current state of the pool water.
Not a fresh fill, though I'll admit that I've replaced some o rings on a valve that was a bit exciting as a check valve didn't work so I'd say a reasonable amount of water is fresh. Checking the swg today there is some new calcium visible on it.Is this a fresh fill of water? You said the cell was caked with calcium in the first post. It has to operate for that happen.

OK -- so this path forward will be entirely up to you.
Your salinity testing has shown, using different methods, that your salinity is around 900 ppm. Correct?
If so, add 2000 ppm worth of salt. Let it circulate really well -- have the SWCG powered OFF during the salt addition. Brush, do whatever to mix it in. Then test it. If around 3000 ppm, start the SWCG.
Warning - if you end up with too much salt, you will have to drain the pool. I am only suggesting this based on the data you have provided.
Your SWCG should not get calcium buildup quickly if your chemistry is close to correct. My caveat to that is if the SWCG is failing.
Best to run the pump several hours, brush, etc. With our high water temperature right now, the salt will dissolve in a flash.
Answering my own question. In the Jandy manual it notes 3000 ppm as ideal, under 2500 ppm can cause premature cell damage, and above 6000 ppm can cause corrosive damage to fixtures.What's the upper limit of salinity without issues? Thinking maybe add a 1000-1500ppm salt, and if it is actually at 3000 ppm would 4500 ppm be a huge detriment?
Good point, I'll run that today.I'd suggest the following: set the cell to max and capture water into a bottle straight out of the return and test that water to see if it's any higher with fc in comparison to another area which doesn't have a direct circulation from fresh return water. This may tell you the bigger picture if the cell is putting out.
Taylor 1766: 2200Good point, I'll run that today.
This 60% may have been with the off cycle but the one in boost is essentially 100% so an FC of 5 makes sense.
