I have a 4,000 gallon AG pool that I set up about 3 weeks ago. I haven't had time to get all the various chlorine supplies I need, so right now it's full of nothing but green tap water. I have ordered some supplies but they won't be here for at least a week.

Anyway, today I scrubbed the sides and bottom so all the green stuff is suspended. How many gallons of 6% bleach should I add to shock it? I don't have any kind of test kit yet...
