anyone have one of these,I got a new one from a guy that never used his, still in box but no manual, I got to look at an online one and still confused. the fluvals got youtube vids and well the fx6 has a video. I notice mine has 3 hose inputs and 2 intake suction tubes. So i suppose you have 2 intakes. but with fluval it tells you in and out, The ehiem doesn't and one of the 3 hose inputs is clear. also no metal rings to tightin. It does have a 2 piece place clamp looking thing. I am still semi new and have only had experience with fluval, this thing just looks cheap and I am just plain stumped. any help or a link to video or quick start up guide
