Here are a couple of recipes I had laying around and thought I'd post up. These are not my recipes, I came across them a while back somewhere.
I personally consider 5% BA to be a bit much since BA is mainly for antibacterial purposes and I don't expect to store it longer than a cycle . I would go with no more than 2% BA maybe even 1% for shot term storage.
