I wonder if it will move fast enough.
Pool_Fool, this is a very key point. I once purchased 10% bleach from a Big Box store. Must have sat around for a while since my test results told me that I had to dose with this "10%" bleach as though it were 6%. Lesson learned. I would favor purchasing bleach from a source with a high product turnover as opposed to focusing solely on the % concentration.
