I've really been struggling with this lately. I changed my homebrew set up to go from a standard airlock to a blow off tube into a bottle of sanitzer a while back. The first time I did it, I noticed overnight that my bottle of sanitizer had gone down quite a bit. I found out that the changes in pressure cause sanitizer to go back through the tube into your beer. After researching this quite a bit I'm nowhere. Apparently from what I've read the same is true with any airlock. I've tried rigging up things like balloons filled with co2 to prevent this to no avail. How do people deal with this?
