I started the SLAM at 5:45 p.m. Friday. At first, the free chlorine was almost completely consumed immediately. The numbers have looked better on Saturday. Unfortunately, for Sunday, I will be out most of the day so I will be unable to maintain shock levels until the evening.
But gosh. I've gone through 22 jugs of 121. oz. 8.25 % bleach already. (Pool math says for my pool and CYA level, it's about 3.5 jugs to get to shock level from 0.) Here are my numbers since starting the shock:

I know that it can take several days to complete a SLAM, so patience is needed. But it would be reassuring to be told that the pattern of my numbers are not atypical. I have a few questions:
1) Are my numbers typical? So far in less than two days, I've gone through enough bleach to go from 0 to shock level 6 times. Just keep pouring in more bleach? I've already cleared off the shelf at Home Depot (though I'm sure they have more in the back).
2) I'm going to be out most of the day on Sunday. And on the weekdays, I'm gone all day and can only be attentive in the evenings. I figure that's "good enough" to finish off a SLAM, but I don't know whether I'm far enough to say that. At the beginning of the SLAM you need to be there diligently raising the chlorine back up to shock level, and I'm not going to be able to do that starting tomorrow. (Only in the evenings.) I hope what I've done isn't all for naught. Is it? I don't want to be wasting effort and bleach. If you tell me that I'm going to have to start over anyway, then I'll just go to maintenance levels and start again next Friday evening when I can go throughout the weekend. But dang, I'm going through a lot of bleach. I think my wife is viewing things skeptically, but she's trusting me so far. So the question is, do I continue SLAMing? Or if my schedule means I can't stay on it throughout the day, should I abandon the effort and resume next weekend?
Thanks. I appreciate the help.
