Ben's response was to stick with the 6 gallon bleach doseage that he initially recommended. With large amounts of ammonia to break down, you're going to have higher than normal combined chlorine to deal with, that can be very irritating and uncomfortable. So..his recommendation was to break it down slowly with the lower doses of bleach, until you start getting CC readings of 1 or 2--at which time you can up the doseage and go ahead and get rid of it. So...stick with the 6 gallon dose for now.

I agree with Watermom on the foaming--it's likely evidence of the algaecide breaking down. Stay the course the way Ben recommended--and we'll help you get it cleaned up!!
