Going to help a friend remove slightly heavier than normal iron staining from a 20,000 gallon pool. We will be using 5 lb of Citric Acid.
The question is by how much will the pH go down if we start at 7.3, per 1 lb of Citric Acid added to 10,000 gallons, and how many ppm of chlorine, will 1 lb neutralize for 10,000 gallons.
Normally I use Ascorbic Acid, however Citric Acid is 50% less expensive here in Honolulu. Is it harder than Ascorbic Acid to re-balance the Chlorine, in other words will we need more.
Although I found this interesting post from chem geek, regarding Citric Acid, pH, Chlorine, and Chloroform, unfortunately no definitive numbers in this post:

And this from Lenntech:

Fortunately we have more than enough wind in Hawaii, most of the time, to remove Chloroform.
Thank you to those that reply.
