Bleach question

[jlg]

My bottle of clorox reads this:

So which % number do I plug into the pool calculator to get my desired add?
The yield chlorine which is 7.85
Or the sodium hypochorite which is 8.25?
Thanks!

8.25 is the number to use.

Even that number is an estimate as bleach is always produced within a range of acceptable %. It might be over 9% when produced by the manufacturer and as low as a few percent if it's been on the shelf a long time.
