Well, it could just be me. But when I first put it together, it didn't work at all. Directions said nothing. Had to get onto UTube. Thank God there was a tutorial online. So I dialed it in the best I could and went with it. It likes to lose siphon, doesn't collect very much at all, needs constant tinkering......I am thinking AquaC Remora Pro on this little 10g. That'll work!!!
