Waterbear, just got back from pool place with a fresh set of numbers...
FC=.2
TC=.4
CC=.2
PH=7.6
Hardness=100ppm
ALK=60ppm
CYA=3ppm
Copper=.11ppm
Iron=not tested
Total dissolved solids=800ppm
.....Looks like I have metal in the pool...so what should be my course of action to keep these stains at bay ?

thanks again for your help
