autotrol 255/440-brine tank

[lizinPA]

Had 4-5" salt bridge below water in brine tank, which water level had been rising for some time. Cleaned out brine tank and started system up again (salt setting on 8, regen. every other day). Now brine tank water level is going up 1 1/2 to 2 inches after each regeneration.

I would appreciate ANY suggestions on what to do next.
