Amounts depend on the volume of your pool.
pH--add acid to lower, Borax or Washing Soda (same as pool store pH raisers) to raise it.
TA--add baking soda to raise, or Washing Soda if you want to raise pH as well. See our ratcheting--aeration method to lower TA (lower pH with acid to around 7 or 7.1, raise pH again by aerating the water--fountain, kids splashing etc).
CYA--Raise by adding CYA. Lower by dilution--drain off water and add fresh.
CH -- Raise by adding calcium flakes or Cal-Hypo chlorine. Lower by dilution.
