I've been using my bottle bucket as my primary for the last 18 batches and have racked to my better bottle than back to the bottle bucket a couple of weeks later to prime then bottle... well now my better bottle has infected my last 2 batches and i'm wondering what everyone else uses. Mind you i'm on a very limited budget and only do 5gallon batches right now. I can find glass carboys on craigslist from time to time but is a 6.5 enough? My bottle bucket is a true brew 7.9gallon and has on occasion seen foam in the airlock
