I live in the Midwest and we close our pool at the end of September and keep the attached hot tub open until December. I started using the BBB method this July after my CYA hit 90 ..did a partial drain to get it down to 70 and hold my target FC at 8ppm (Have the TF-100). The pool looks great since doing this. In the past two years having this pool spa when closing the pool I would put a chlorinator float in the hot tub with a tri-chlor puck in it. Before I use the tub I usually throw in a 1/4 cup of dichloro shock from Leslie's. Anyone have any sugesstions as to the approach I should use with the BBB method?
Thanks In Advance!
