No, no boilover (or return to boil for that matter). I took off the flame with about 6 gallons left. My IC only brings the wort down to about 100 degrees (I'm thinking of using a prechiller, any suggestions?). I cooled it to about 85 and than began to aerate by pouring the wort from bucket to bucket. I got it down to about 79 degrees and pitched. The fermenter then went into a cooler of water with a towel and a couple of frozen water bottles. Checked it this morning and the airlock is bubbling
According to Brewsmith, my efficiency into the boiler was 77%, I'll take that for my 2nd AG!
