New to BBB and have a question about Best Guess Chart

[Armytiger]

Thanks for the info and the equations. So if my CYA is 30ppm and I'm going to shock my pool. The chart says shock 15. Does this mean that I want to raise my cl levels to 15 ppm or a 15 ppm dose?

You raise the chlorine up to 15ppm.

So, if your FC is 0, or even .5, you'll add chlorine to raise it to 15, which will be adding 15

But if your FC is 6, you only want to add 9ppm of chlorine to raise it to 15.

Uhhh ---- isn't that what I said above??

I just wanted it to be clear for ArmyTiger that it depended on the starting point.

I was just a little less terse/cryptic!

Watermom . . . I understood

Thanks to both of you for your explanations.
