I have a three-tier 10gal More Beer system that also runs on the SMART (recirculation at mash). My problem: The grain is getting stuck at on the top of the false bottom while attempting to mash approx. 8lbs grain with 2.25 gal water. Is this too little to use for such a large pot (10gal)? I was attempting to do a small 2.5gal batch total to work on my system efficiency. Or, was this not enough water for the mix and it just got clogged? Or, should I have used a 5gal pot?
