Req for comment on high calcium numbers

[docwalker]

I've read just about every posting related to high calcium numbers and mine seem excessive. I've tested 4 times over the past two days. I even tried wiping the tips after reading about the droplet problems related to the new PS234 kits.

15,000 gal IG plaster/gunite pool/spa w/gas heater, 60 ft2 DE filter
5.25% bleach (2.5-5.0 gal/week) fed automatically w/LMI diaphragm pump and controlled by programmable controller

POOL:
FC: 6.5
CC: 0
pH: 7.5
Alk: 90
Cal: 650
CYA: 40
Temp: 88 degF

TAP WATER:
FC: 0
CC: 0
pH: 8.2
Alk: 70
Cal: 100

My water is crystal clear and haven't had any trouble maintaining FC or pH. I've been using the test kit that came with my pool and have never measured calcium before receiving my PS234. Should I be concerned about the Cal? Is it worth flushing/diluting?
