Thanks again.

Don't get me wrong shay, like I stated above, the ladder is about the best passive diffuser out there. It does work. I have had good results running two 2 liters on a ladder and not had the problem mentioned above (I always had about as good of dissolution as possible with the ladder).
As for the submersible filter, I wouldn't see where it wouldn't work. Really all you are wanting is a good flow of water to churn the bubbles around in the gravel vac. As long as the filter gives you a good output into the gravel vac I think it should work.
