Have been using the BBB method for two years and it has been great, CYA was about 100 when I started BBB and this year I filled the whole tube and the dot is still there so it is less than 20. I have a chlorine pac left from two years ago I would love to get rid of, it is trichlor about 5 1/2 pounds in the pac. Seems like the perfect opportunity, what do you think? How much of it would I need to consume to get from say 10 to about 40 or 50 if I go this route?
