The Remora is an injection skimmer, no venturi or valves to adjust. Micro bubbles will occure until the skimmer breaks in, it took mine a couple of weeks (though it started to skim on day one.) AquaC also makes an overflow box designed to eliminate microbubbles on the remora and remora pro, I believe marine depot sells them. If your tank is big enough (mine is a hex and it won't fit.) I however, have a buddy that has one, and it appers to work, I have never hard him complain of micro bubbles. You might also try putting a sponge in the spillway.. .haven't tried that, so not sure if the sponge would effect the skimmers workings or not.
"Maybe in order to understand mankind, we have to look at the word itself: "Mankind". Basically, it's made up of two separate words - "mank" and "ind". What do these words mean ? It's a mystery, and that's why so is mankind." ~ Jack Handey
