Needlewheel to Meshwheel skimmer mod

[fishface]

update: i wanted to try the enkemat again so i gave it a shot today and i have to say, i gotta eat my words. i remounted this stuff and trimmed the edges more and i AM getting larger amounts of and smaller bubble production. i also noted that taking the valve off of the venturi line increased bubble by perhaps 10-15% as well. thanks again Tony, glad i revisited this mod!
