Just started the BBB method and testing with Taylor K 2006 kit.

Here are the readings:

PH 7.4
FC 9
CC 0
TA 120
CH 320
CYA 100 + by the kit. Pool store says 135.

I'm using 6% bleach and trying to get the chlorine level up based on Ben's Best Guess, 8 to 15.

Yesterday I tested at 9:45 am with FC of 5.5. I added 1.35 gallons of bleach. 12:15 pm tested with FC of 10. 7:20 pm tested with FC 0f 10. Added 1.35 gallons of bleach thinking I would get close to 15. Did not test again last night but tested at 7:40 am with FC of 9.

Should I just keep adding and testing trying my best to hold it at 8 to 15 or should I try shocking up to 25 level?

I live in Central Texas, 100's every day and surface temp of pool is 90 degrees.

Not sure what my next step should be.

Thanks in advance for the help.
