I started my conversion to BBB with two partial drains that lowered my CYA from 100+ to 35. Then I started slamming to a shock FC of 14. As expected, there was a big initial consumption of FC. It measured 5 after 3 hours. I only did one more shock that first day. I now know that I should have done more. Anyway, my first evening/following morning reading was 14.5/2. The next day I hit it 4 times, and the reading that night/following morning was 14/8 so I was encouraged by the progress. But the next two nights/mornings have been 12/8 and 12/7.5. Because of work, I am now able to shock just twice a day...once early AM and once late afternoon.
Other info--the water cleared within 2 days and looks spectacular. We can also feel the difference on the fiberglass finish...no more slimy feel. Even the Dolphin bag is different...no more "muck" that had started to hold the water when I cleaned it.
Should I stay the course or alter my strategy somehow? I was planning on closing next week but would love to get this water right before I do.
