I added gelatin to my keg today, just like Don Osborn did in the youtube video(this guy is awesome, watch his stuff!) probly about 4 gal in there. very cold. Ill wait until the day after tomorow and report back what happens. I can do a side by side comparison- I have 2 5 gal batches of the same beer, both about the same murkiness. Should be interesting.
Cheers!
