Probably not. I usually add with 10 minutes left in the boil to dissolve/sanitize.
10 minutes out from flameout is also when I kick the March pump on to recirculate through the CFC and tubing to sanitize and drop in a Whirfloc tablet, so it's a convenient time for any adjuncts that I may be adding.
