Non-chlorine sanitizer and equipment

[markeast]

Just to let you know, I'm following this routine with success while waiting on the pool builder to switch me to a salt water system. The ph is staying around 7.4, and the copper is around .4 (down from .7). The water hardness is around 150 ppm - should I add calcium chloride to make it higher?

Your only hardness issue with a vinyl pool should be what your heater manufacturer recommends.
