ya i dont think the remora has the air adjustment, bc i think it just shoots a jet of water that then hits a plate to break it up (not really sure though ha). But is the skimmer pulling out scum, bc if so you might let it just do its thing and it should slow down after a couple days. Also if its new they will have oils in the skimmer from it being put together that can cause excess collection, but the same thing has to be done, just let it run and it will slow down after a couple days.
