How much bleach to shock 8500g

[CToon]

Hi Gerri

First , you dont have to buy "shock" , bleach works great . ( shock is really just the action , not the product)

Second , keeping at 3 ppm for a cya of 50 is ok minimum . I coppied the best guess chart into notepad and put it on my desktop so I always have it. comes in handy for a quick check

With cya of 50, free chlorine should be kept between 3-6 all the time.
