How to calculate 2-part additions

[Tautog]

I have a total tank water volume of 200 gal.
My Alkalinity drops .5 dKH / day
How much Soda Ash solution ( BRS 2- part) should I add?
Is there a specific formula?
Thanks in advance Randy

Brs has a calculator for their 2 part. Found here https://www.bulkreefsupply.com/reef-calculator/

Enter youre current alk, what you want youre alk to be, And tank volume, and it'll tell you how much to add

You can also use this calculator for a wider array of additives:

BRS using sodium carbonate is my DIY#1. Using the calculator, you need about 71 mL.

This works pretty accurately for me
