What kind of formula and does it apply to our aquariums?
I wrote a formula that directly applies, and it's in the first post.

For simplicity, here it is again;

(((A)*3.785)/(11000/((B-C)/2.8)))*1000

A is the amount of water in gallons you need to affect. IE your new Saltwater.
B is the Alk reading you achieved from your test kit of your new Saltwater.
C is the Alk reading you achieved from your test kit of the water you will be adding this newly mixed saltwater to, or the Alk reading you want to match.

Something I forgot to mention in the first post is, A is in gallons
