I have used the Gas Law process to reduce TA. With the Taylor K-2006 I now get these results:

FC - 1.6
CC - 0
pH - 7.6
TA - 100
Ca - 240
Cya - probably 20 (test shows < 30)

23,000 gallon In Ground Plaster Pool
2.5 Hp two speed Hayward pump
48 Sq. Ft. D.E. Filter

I'm still working on raising Cya. I also dropped 80# of salt in but haven't had a chance to try it out.
