A simple DIY bubble counter between the yeast CO2 generator
and the CO2 reactor may eliminate your problem. (i.e. you can
let the CO2 bubble through some water and trap the fungus-like
Mine is something like the figure below, made of a little jam
jar holding 50-100ml of water.
I actually made 2 holes in the cap, and fixed plastic airline
joint for each inlet and outlet, then connected a short plastic
pipe to the inlet inside the jar. It was a 5 minute DIY work.

counter and got the white fungus-like growth. It's gone by
