i have a bucket and carboy sized for 5-gal batches. if i scale down to 2.5-gal, will the empty space cause problems?

Here is a link to a 3 gallon waterbottle that you may want to look into. Its cheap and would really help you. If you want to scale down I definately recommend it because its cheap, you can use the spring water to brew with then use the bottle (wich is PET - same material as Better Bottles) and its the perfect size for 2.5 gallon batches.

To answer your question you can do it but its not to be advised.. with all that headspace there are numerous things that could go wrong. ( infection, oxidation, etc.) but its not unheard of or impossible to do.

In the above link be sure to note that brand will vary by area. I have a water cooler and get my bottles from Lowes. Big #7 on the bottom, not PET.
Primary - Beer
Primary - More Beer
Secondary - Still More Beer
Kegged - Yet More Beer
Planning - A Bunch of Beer and some mead

I always forget to update this thing, so the above should in general hold true.
