Should I raise CH?
Just recieved my new kit which includes all the important test, so I was able to do the whole spread:
FC= 2.4ppm
CC= 0.0ppm
TA= 110ppm
CYA= 45ppm
CH= 150ppm
Now everything seems spot on except that last one. I have a gunnite pool with stone aggregate finish (not plaster). To get it to 200ppm, according to Bleachcalc, I would need to add 9 lbs. of calcium chloride. Should I do it? Another question, if I were to add it, does calcium ever leave water or is it in their permanently like CYA?

Re: Should I raise CH?
Calcium levels generally only go down as you replace water, depending on the CH of the fill water.
Since you have a gunite pool, you need more calcium. You can add it directly, or you can chlorinate with cal-hypo--only use the 68% chlorine type. It will chlorinate your water nicely, and add the calcium you need, albeit slower than directly adding it. Still, by sometime in the season you should be well into the 200-400ppm range and can stop.
