Use one everytime. The first time I actually used a blow-off tube I needed it. Stuff went all the way out of the tube and into the container I had the water in. Now I use one all the time. All you have to do is buy 3 feet of 1/2" ID tube (I believe) from Lowes for like $.50 and you're done. Take the airlock apart and stick the tube in there. It works well.

Brewed up a "Phat Tyre Amber" all-grain clone yesterday...and I'm really, REALLY, R-E-A-L-L-Y glad I always use a blowoff! I would have had fermenting wort all over the place! The fermentation was extremely vigorous, with some krausen foam in the tube itself. It's calmed down now, but it would have been a major cleanup!

I used to use a blow-off tube but the tube plugged once and exploded anyway. I started using the airlock, but just setting the lid on the bucket without snapping it down. Haven't had a wild fermentation since I started doing this, but it should work OK. I think it would just gunk up the swamp cooler tub, but that should be easy to clean.

I always thought they should sell lids with multipe airlock holes. One bucket with multiple airlocks. Or big fat airlocks and a bigger hole.

Even though it hasn't often been necessary in my 6.5 Gallon carboy I am using a blowoff tube every time. My tube is not a exact fit, so I seal the top by wrapping it up with cling-wrap soaked in sanitizer then secured tightly with tape. I install an air-lock when it is racked to secondary.

I use one all the time now. I brew 5 gallon batches in 7.5 gallon fermentation buckets and I haven't had any issues with head space so far as I can tell but I figure, why take the risk? So I put a blow off tube on everything I brew.

Interesting idea. I guess you could just drill a 3/8" hole and pop in a grommet or something.

I always do primary fermenting (5 gallons per) in a 6.5 gallon carboy and I have never needed an airlock.....until I started to pitch yeast starters. I have had an airlock fill with krausen, I promptly changed to a blow off tube.

Just this weekend I checked one of my carboys with a Cream Ale and the krausen had pushed the airlock right off the carboy, while the other carboy with the same Cream Ale (10 gal batch split between 2 6.5 gal carboys) only had an inch of krausen in it. I changed both to blow off tubes and will be using blow off tubes during primary from now on.
