I shocked my pool and got the FC to 1ppm. My ph is low at 6.2, I added baking soda (not sure if this was right!). Can't test that again for another hour. When do I add more bleach, and when should I use borax? Also, my water hardness is low...what's the best thing to add to bring it up? My CYA is zero...I didn't want to put stabilizer in with shock. Oh, and my alkalinity was 0 when I tested.
