Redael,

That calcium level is gonna' be problematic. I have no personal experience but, if it were my pool, I'd work on lowering it. The two possibilities I see mentioned on this forum are 1)partial drain and refill if your fill water is acceptable and 2) use of a water softener to remove the calcium.

Since it appears to be a regional problem, local pool companies may be able to give you some assistance based on their experience.
