Protoflox and purebrew

[Libigage]

Hi, if I use protoflox in the boil can (or should) I still use harris pure brew in the fermenter

Use Protofloc in the boil approx 10 minutes before the end.
You can use other finings clearing agents in the FV which tends to work better with a cold crash as well, so the answer is yes. I usually use Protofloc in the boil and Gelatin in the FV but any clearing agent of your preference can be used
