well, my experiment with this provided to be unfruitful and about a waste of at least an hour of my precious time
. i tried a combination of christy's and bill's attempts, by that i mean i used gutterguard cause i didn't have the enkamat and i just put the layers over top of the needles cause i was paranoid and didn't want to potentially kill an impeller.
end result was that the skimmer worked fine this way but there was in no way any improvement in performance or bubble production. just one persons experience here...i guess sometimes ya just have to go for it huh?
