I wonder if this would work? I'm thinking about talking my c02 line and tying it into the sucktion side line of my Eheim filter, the c02 would be sucked into the filter thus eliminating the reactor, any comments are welcome.

That's how I do it - it works pretty well, at least w/ the classic series (these have higher flow ratings than the Eccos etc.).

I do the same, but use a limewood airstone to break up the bubbles first, right before the filter intake.

If you do a search, you should be able to find other threads on this.
