working with Randy's calculator

[Sango-chu]

fGentlemen of the forum, I am currently using randy's 2 part solution. I ordered calcium hydrate from one of the links and they sednt me calcium andryous in its place. Randy's article talks about using it as well but in a smaller dose. My question is: The artilce talks about 5 cups and then going to 4 cups but the receipe states that I should use 1 cup (20% less because its andryous) to 1 gal of water - what shoudl I use - 1 cupo or 4 cups to a gallon.
2nd question: When I go to the dosing calculator, it offers me two option for dosing calcium - in the top part it states calcium andryous and alittle lower down it offers me randys 2 receipe (which I am using because my pH is high) question is: Which calcium product should I be using from the frop down box?

if the andryous, how do i mix this form of calcium?
thanks in advance,

For the low-pH variant, it's one cup of anhydrous calcium chloride and enough water to make one gallon.

For the drop-down box, the label is "Randy's Recipe 2 Calcium Part", on the traditional version:
