I posted this reply to your other post.
I, personally, wouldn't purchase CH from a "chemical supply house".
What you want is as pure of CH as you can find.
I don't know if they make "food grade", or not.
Where I get mine they say it is "78% calcium hypochlorite".
The link you provided says "65%".
I don't know what the difference is.
What constitutes the other percentage?
I mention my source on my website, link below.
They are a well-known and well-established "MMS" source.
So I feel safe purchasing from them.
