What is the formula underlying the Pool Calculator?

[gatorbrit]

As my pool volume doesn't change, I thought I could create a spreadsheet using the formula in the pool calculator. It would be a grid - along the top is my target FC along the side is my current FC. Each cell would have the amount that I need to add. I could then print it off and put it in my test kit box, and that way i can easily look up what I need to add.

My question then, is - what is the formula that tells you how much bleach to add to get from actual FC to your target FC?

Someone just posted that in the "Deep End" forum. It will change based on several factors, but you'll get a feel for it and not even need a sheet in time.

OK thanks - I see it now... Here http://www.troublefreepool.com/blea...nit-volume-and-other-calculations-t69102.html

Bit more complex than I imagined!

Yea, but honestly you will develop a really good feel fow how your pool reacts to additions. Promise.

Is it possible to get Boric Acid added to the adding effects section at the bottom of the calculator?

Not likely, if it isn't there, the people who own it now do nothing with updating it the last I heard. Perhaps someone knows something more recent.
