This isn't working, I set it up like mentioned above. I ran the bubbles through the powerhead, they ran into the "diffusion chamber": a gravel vac filled with bio-balls, but then I got tons of tiny dust-like bubbles coming out the other end. Even if I am diffusing CO2, I don't like the bubbles, they look like dust and since there are so many, I don't believe this is much more efficient. I'm thinking if I got a smaller powerhead it might work, but if I can find something that will trap these bubbles, that would be even better. Any suggestions?

Tank in transition! 55 gallons, hard water.
