A shocking question

[aylad]

You need to shock to burn off combined chlorine--chlorine that has been "used up" by sanitizing gunk in your water. So when you have CC over .5, or 0 CC but visible algae, or cloudy water, shocking is the first step to getting it cleared up. If the pool chems stay where they need to be, all the time, you'll rarely have to shock.

That being said, I also shock after a large bather load or after a bad rainstorm.

How much ppm do you have to raise the chlorine to in order to shock? Now that I am on bleach I have been wondering about shocking with bleach. I seems that you would only have to add more but I may be wrong.

Ok, my CYA is around 50, thanks that helps. I will have to do a dilution test in order to test for levels that high though, I need a better test kit. lol
