First of all, first post and glad to be here. Pool is 30+ y/o concrete approx. 37K gallons well maintained through the years. Pool was opened and treated by local company this Spring and they did a great job getting it to swimming condition. I'm looking eing said, pool seems happy to use the BBB method this season and looking to share stats for some advice on the next step.

pH: 8.4
Chlorine: total- 9.5 Free-7.8 (20 hours after shock) .3 and 0 pre shock
Alkalinity: total- 122 Free-99
CYA: 76

With the above being said, the pool seems happy (before shock anyway). I have the following questions:

1) How long after shock should I expect the chlorine level to equilibrate back to maint. levels (given typical NE weather)?

2) How much should I fight the pH? (I read the cited article about a higher pH and my take is that I should adjust the alk and chlorine and let the pool reach its "happy" pH).

3) I have not found "doses" of the BBB's to start off (per 10,000 gal.) anyone care to make suggestions (no borax for now...I know)?

Again, thanks for reading and look forward to learning a ton this season....and hopefully not having any huge issues in the process.
