Formula for lowering Alk using Muriatic Acid

[Myka]

Success! ...besides the carpet! Also keep in mind that muriatic acid will also damage stainless steel - it stains it a dull grey color.

I didn't read the whole post as its really lengthy but I use hydrochloric acid everyday at work and we take full precautions when dealing with it. it comes in at 33% but will decrease with age. I have a formula I use if you wanted it

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
