I have begun using fermcap. It eliminates the need for a blowoff tube.

I leave the blow off on the entire fermentation; no need to swap it unless you need it for another batch. However, I would recommend switching it for an airlock before cold crashing or as others said it will suck back into the fermenter DOH lesson learned.

thanks for all the responses. the bloop bloop noise doesn't really bother me, it bothers my wife... I am half deaf but I can hear it in the kitchen from our bedroom - probably the tile floor in the kitchen intensifies it. but you talked me into it - i'm not touching it. at least for 2 1/2 weeks, and then I will rack to a secondary (if the specific gravity has not changed for several days) for dry hopping for 3-5 days, and then bottle, ideally at 3 weeks. i am just trying to go off of all of the great advice I've received off of this forum. I want to try a secondary this time because shoving hops into the primary last time was a mess. does this sound like an alright plan?

I've never used a blow-off, though I did make a batch of barley wine once that could really have benefited by it.

Once "high krausen" has come and gone, you can safely switch from a blowoff to an airlock. The "danger zone" has passed by then.

I always use a blowoff. No extra effort, and all the extra security in the world. They are different versions of the same concept, and I can't figure out why one is "nooby" and the other isn't. Every fermentation is different, and I refuse to run the risk of having to wash krausen spackle off my ceiling, when it is SO easy to prevent.

I cold crashed once with an airlock on and still had liquid pulled into the fermenter, though it's a small amount. I haven't tried cold crashing since then, but when I do it again, I'm only using sanitized foil over the carboy mouth from here on out. Bactera and wild yeast just aren't going to crawl up and around the foil to get into your beer, possibly a fruit fly could I guess.

I always leave my blow-off on for the duration of the brew. There's really no reason to change it out for an airlock, unless it's something that you're bulk aging / lagering for a really long time.
