After some much needed rain this weekend, I need to raise both my TA and Calcium. I'm going away this weekend, so I need to shock the pool Thursday before I go. That leaves me with tomorrow and Wed. to add chemcials. My question is, which chemicals should I add first? If I recall, the Calcium stuff you have to add on a day all by itself. Pool is 12,000gal exposed aggregate surface. Here are some numbers from my testkit:

CYA-~45ppm
TC-6ppm
pH-7.5
TA-50
CH-180

Thanks!
