I had cement patio pavers installed around my pool this week. I know I should have had the pavers done before the pool was opened but that's another story. Anyway now I have tons of cement dust in the pool and I can barely see the bottom.

I ran the pump until the fliter clogged, cleaned it and ran the pump some more. I'll probably need to clean again tonight. I added Muratic Acid last night to lower the PH (was 8.0+). Pool is still cloudy and there is still some dirt on bottom.

What do I need to do to lower the Ca in the pool? My readings this morning are:
PH 7.5
Alk 200
CA 300
CYA (didn't test - has been 40)
CL 0 (added a gollon of bleach)
TEMP 84

Its a 18 to 20K inground gunite pool with Diamond Brite type finish. Thanks.
