yeah i have pfs in all my tanks but one, which will have it soon... it is amazing. I can take my python and shove the gavel vac all the way to the glass and then lift it back up and i never have it in my sink... I have heard from some people that they just skim over it, but i do it the same way as you do gravel... I dont keep mine very deep, around 2", but my mbuna manage to pile it up in some places pretty deep. Pfs is course enough that you really dont have to worry about gas pockets building up like you do with smaller sands.
