:P well yeah, but your sump would have to be higher then the bucket right? If its on the floor then what? I'd imagine either suck out the crud bit by bit with a turkey baster or else a small pump in reverse. I dont know how a gravity Fed siphon would work without gravity
Also yea skimmers are dirty work. Try getting your hands inside a tunze 9002 to clean it lol. Not pretty oh well, at least its a small unit to clean.
