I guess I'm all set. Since I wasn't clear in my OP that I was not trying to clear up algae, and since Watermom's sticky is addressing algae, I wanted to make sure I had it right. I was looking for clarification between "it won't hurt" and "it is recommended." I'll just bring it up to around 25ppm (496 oz of 8.25% bleach!) and be done with it. Thanks all.
