I have 27' x 4' Roung AGP with 24" hayward sand filter and 2 speed 1.5 hp pump. New pool set up showed no FC, no CYA, TA at 325, PH 7.0

Using BBB method so added 128oz bleach, 4lbs CYA, 92oz Muriatic Acid at 31.45% and entire box of Borax based on calculator through another website.

2 days later Tested again using Taylor k2006 kit and now have:
CYA 50
FC 1
TA 325
PH 7.8

Not sure why TA is not lowered.
