Chlorine vs. Bleach

[npholt1]

First off, I feel fortunate to stumble across this site after dumping $$$ at a local pool store for chemicals
Now, I am stuck on the math of Big R liquid "pool shock" (10% chlorine) vs walmart bleach (6%). The shock goes for $2.25/gallon and the bleach for $1.79/gallon or $2.54/1.42 gallon. If I am guestimating correctly, I would need 5 gallons of bleach to match what would be in 3 gallons of the shock (is this correct thinking?). Therefore, it would cost me $6.50 for shock and $8.96 for an equivalent amount of chlorine in bleach form.

Please correct me if wrong!!!

Thanks

Check out the pool calculator on this site it is very helpful in figuring out what you need for chlorine.

Exactly, 3 gallons of 10% equals 5 gallons of 6%. Clearly where you are, the 10% is the better deal.

Note that most bleach is sold in either 3/4 gallons or 1-1/2 gallon containers and not in 1 gallon containers.

Exactly, note that I mentioned what is above in the OP. Breakdown came 1.4 cents per fl oz for bleach and 1.7 cents for chlorine.
