Please help me set my pool for swimming. I got an Intex 16'x48" pool (5000 gal.) for the grandkids. Set it up and filled. Per your preliminary instructions I added 2 qts chlorine bleach and 1.5 lbs CYA. Using test strips, my readings this afternoon are:

CYA 10ppm
Total Alkalinity 0
PH 6.8
FC 5 ppm
TC 5 ppm
Total Hardness 50

I know I need to add Borax - how much do I need? What else do I need to do? Please help - the grandkids are anxiously awaiting the OK.
