Oh wow ... congrats on the FX5 ... I hear they're awesome. Although I don't have one, it's not too much of a droop. Hopefully someone that has one can better comment. I would think when they say no loops the figure either letting it droop to the floor to then up to the tank, or actually having the hoses form a loop ... IMO
