Hurricane Gio - I had the same problem with my Aqua Rite and I believe the issue is that my cell went bad.
I kept getting low salt readings and would add more and then it eventually stopped working. So I took a water sample to the pool store and they tested it at 5000 ppm, so way high.
I read later that as the cells began to go out you could keep them going a while longer by increasing the salt level - but then eventually they quit working - which mine apparently did.
So depending on how old your unit is - mine was 4 years old, I think - that may be the problem.
I have been dumping water now and adding back fresh to get the salanity back down to the 3400 range.
Now I am in the process of getting a new cell for it.
Lots of luck with yours.
