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?
Most places don't sell 6% bleach. Typically it is 8.25% now and not a full gallon either. I buy Walmart's generic 8.25% bleach in a 121-oz jug and it was $2.94 yesterday when I bought some. (8/2/14) I have a feeling that most of our 'bleach-users' are also buying Walmart's bleach.
I buy liquid chlorine in five gallon carboys, currently for $19. It nominally is marked at 12.5% but tests at 14-14.5%. So it is like getting 7% at $1.90/gallon.
We have had the per-pound levels of chlorine listed on PF for di-chlor, tri-chlor, and various concentrations of cal-hypo, but I don't remember them. I do remember that di-chlor releases as much CYA(stabilizer) as it does chlorine and tri-chlor releases 60% as much CYA as chlorine.
