I was getting a little concerned because people kept talking about $1/gallon bleach, and I don't think it exists any more. (The cheapest I can prove exists right now is $1.50 a gallon.)

I found a thread on another forum about the different levels of chlorine in different chlorinating products. Someone there mentioned it would be nice if someone made it into a spreadsheet.

So, I did.

But I'm not sure if my math's right. Could someone please check if for me?
