My surface agitation isn't what I'd like it to be. I have the Flow from the Remora skimmer (maxijet 1200), a HOB filter, which usually has no filter in it, an AquaClear 30, and an AquaClear 40 or 50 (i dont remember which).
I'd like more surface agitation though.
I also think I should put the filter box back in for the remora. I think it makes it more effective, even if its pretty big and ugly.
