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?

Yep. I've used 3 gallon primaries for a few half batches... worked perfectly!

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.

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.
