You'll probably have enough headspace with that large a fermenter. I always rig a blowoff during the first 3 days of fermentation or so, but I ferment in 6.5 gallon buckets exclusively. All you really need for a blowoff tube is a piece of 5/16" tubing a few feet long and a bucket or jug with sanitizing solution. The tubing should fit through the rubber grommet in your bucket lid and the other end goes into the bucket. It will also fit through a rubber stopper hole. When fermentation slows down, just replace it with your airlock. I've only had one batch blow off, but peace of mind is worth alot to me.
