white feathery stuff

By the exit of my co2 tube going into the co2 latter there is a build up of white feathery almost ghost like looking stuff, what is it?

I used to get the same thing on my bubble ladder when I used DIY CO2. It is most likely floccuated yeast. Add a gas separator to your setup and that should solve the problem.
