I've been using the usual bleach or H2O2 method for cleaning my inline CO2 diffusers.
I saw this method on another site.......
"you can unscrew CO2 input line, add liquid carbon with a syringe and leave it overnight. In the morning when CO2 comes on it will slowly push the carbon out and clean the diffuser"

Has anyone here heard or tried this? I couldn't find any history with a forum search.
