Depends on the filter. I use Fluvals, and the impeller is located at the
top in the lid...not the base.

Not to mention the extreme amounts of co2 that build up inside (due to air
bubbles here and there) the could be harmful to the bacteria. I'm not
saying all of your beneficial bacteria are gonna die, but they may not
perform at their "prime" so to speak.

Since the motors are located in the base (under the water column)
I don't see how that would happen. It would take an awful lot of
CO2 at VERY high pressure to force all the water in the canister]
down to the impeller and up the outlet tube.... I think it's a safe
way to do it.

Until an air pocket builds up one day while you are gone and causes your
impeller to overheat and seize......

It looks good in black and white though.

I just feed my CO2 tube into the inlet of my canister filter... This
has
been the best method I've seen yet!
