I used the calculator to get the following information for your 19,000 gallon pool:

3/4 gallons of 6% bleach -----> 2.4 ppm chlorine increase
1 gallon of 5.25% bleach -----> 2.8 ppm chlorine increase

4 ounces of sodium bicarbonate -----> 1 ppm alkalinity increase
6 ounces of borax -----> 1 ppm algaecide increase*
1 pound and 8 ounces of cya -----> 10 ppm cya increase

15.2 ounces of sodium carbonate -----> 0.2 ph increase
19 ounces of socium gisulfate, dry acid -----> 0.2 ph decrease
15.2 ounces of 31% muratic acid -----> 0.2 ph decrease

*(for calculating how much borax to add to fnction as an additional algaecide, not phchanges - recommended target level is 50 ppm) I use the polyquat algaecide myself.

Mostly, around the Dallas area, the "ultra" - 6% - bleach bottles are 3/4 gallons, while the regular - 5.25% - bleach bottles are one gallon.
