Shocking with dichlor... there's a recipe for that!

The recipe is called Default dichlor

It’s actually not a great idea to shock the pool with a stabilized chlorine (see red text on page 4):

However, many pool chemical suppliers sell dichlor as “shock”, many users have asked me to support this, and I can’t spend my entire life screaming into the wind. So, I made a recipe for it in pooldash (linked above).

This recipe is a close mirror of the default recipe, except it replaces calc-hypo with dichlor (dichloro-s-triazinetrione). It also attempts to adjust the CYA recommendation based on the effect of any dichlor used… but I’d love for someone else to review it, if you’re so inclined.
