Thanks so much for clarifying the difference between Ascorbic Acid and Citric Acid. This has all been so confusing and stressful. I really appreciate your tips and cautions about combining Citric or Ascorbic Acid with Chlorine. I did additional research after your reply and found this Ascorbic Acid, Vitamin C Powder - 11 pounds for $59.99 with shipping to me in North Carolina of just $1.89. That's just $5.63/pound.

Ascorbic Acid, Vitamin C is what got me the beautiful pool water we now enjoy. Thanks also for the tip about Polyquat!
