I run CO2 into my Eheims without problems, but have had the "airlock" a few
times.  IME, it isn't from the CO2, but rather from not priming it properly
after cleaning and/or having a bad seal at the o-ring.  Sometimes air gets
trapped in the media and then locks up the filter once you leave it un
attended.  So, you could try a little silicone on the o-ring and re-priming
the filter.

HTH and hope the plants I sent you aren't too covered in slime!! :-)
