I used biofine on my last keg without a problem. I bent my dip tube a little bit.
I added the biofine to the beer just after racking in to the keg. I use a carb stone to force carb so I am sure it stirred up the biofine pretty well.
I will also note that my beer was crash cooled in the fermenter so it was cold when I added the biofine.
First pint was crystal clear.
