I've found the ph level drops in a few days, up to a week. But I'm also always refilling the pond with well so my waiting period is much shorter as I'm diluting the lime. Easiest to drain as much as possible with siphon so volume is much lower and easier to nuke with lime. I'd even go so far as to seine remaining pools to ensure you have everything. I've limed fisheries 4 times now, learned something new every application. So far so good, but have to be careful and detail oriented.

Many men go fishing all of their lives without knowing that it is not fish they are after. ~ Henry David Thoreau
