OK - I have been adding Mule Team and chlorine as well as pumping out water ...today readings:

FC = 20
CC = 0
pH = 6.8 (still after 4 boxes / 16 lbs of Borax)
TA = 60 (this seems to be going up)
CYA = 60 (down from 120)

Still blueish clouds in the pool and I have to rinse off my cartridge filter every couple of hours - caked in some royal blue stuff. Any idea what that is?
