i use an up aqua atomizer for a couple weeks now. works really good. cant say much that would help you. i run it through about 5 feet co2 tubing, 2 cheap check valves, and into an eheim 2215 @ 35-40 psi from a milwaukee regulator. the only time i thought it wasnt working was when my eheim flow cut down to almost nothing because my prefilter was clogged.
