So i just seen at work we sell AquaClear 110 Power Filter for $89 or so, i think. Seen this does 500gph but i couldn't find much other info on it. Ive been told its very silent. One of my questions is, does it have an extender tube, i dont need to suck up my newly filtered water nor do i need to suck water off the surface, tho i really liked that idea. I dont want to be sucking up the clean water.
