can i use a blow off tube on my secondary if i don't have the proper bung for an airlock on a Better Bottle?

also, should i worry about oxidation because of the extra air space in a six gallon BB that i'll be using for my secondary?

Why are you using a secondary? Are you doing a fruit beer, dry hopping?

Some people just like to secondary.

If you do choose to use a secondary/bright tank, yes you can use a blow off tube, just make sure its going into some starsan, but I doubt there would be any suck back in secondary.

As far as the headspace goes, if you rack it properly and don't expose the beer to air, it will off gas plenty of CO2 that should fill up the head space.

Why not get the proper bung / top to ensure a tight fight?

Exactly. And get a proper airlock, there is no need whatsoever for a blowoff tube on a secondary.

blow off tube and airlock are essentially the same thing. and as far as the other question, they sent the wrong bung and i'm not paying shipping for one little piece of rubber. i'll get it as soon as i order more ingredients and/or equipment.
