 I have three Eheim Eccos and they do not take too kindly to having CO2 injected
into them.  One actually seized up and got extremely hot due to vapor lock.  This
filter was damaged to the point that it had to be replaced.  The other two would
get the "rattles" quite frequently.  I have since ceased injecting CO2 via my
Ecco's.
