Default 2.5 Gallons batch in 3 gallon carboy?

I want to start to make smaller batchs so I can do some experimenting and comparisons. For a 2.5 gallon batch can I use a 3 gallon carboy as a primary fermenter?

Sometimes you need a blow off tube, but I usually just switch out the airlock when it gets full of junk.... I've been doing 2.5g all-grain lately, primary in a 3gal BB.
Check out my Homebrewery Virtual Tour!

Who says you can't brew all-grain indoors?
Brewing 2.5 gal batches with a 2gal cooler MLT in my cramped apartment. Pictures coming soon!

Ask me about my Keezer/2.5 gal brew setup!

You could also do your 2.5 gallon batches in a 6.5 gallon fermenter bucket if you have one. They work great and you never have to worry about a blowoff tube.
