I am using the Nutrafin Bubble Diffuser/Counter with DIY CO2. The
system works great in diffusing the CO2 bubbles into the water. The
only problem is a rather quick and significant build-up of a
white-string/slime at the exit from the tubing into the diffuser that
also creeps up the "rungs" of the diffuser. I researched this on the
Internet and have tried adding an intermediate separation chamber
between my CO2 source and the diffuser. This chamber is a glass jar
where the gas enters at the bottom and exits at the top. I have tried
this separation technique with both water and no water. I have also
tried plastic beads in the chamber to give the "slime" a surface to
adhere to. All of these attempts have failed; I still get the quick
buildup of slime on the diffuser and no slime in the separation
chamber.

Does anyone else have this problem and has anyone found a solution?

Thanks in advance for any help you can give me.

P.S. I am cross-posting this question to several groups to get some
wide-exposure and hopefully a solution to this problem.
