Review on Aquarium Water Outlet Nozzle: 360° Rotatable, Long Duckbill Pump Pipe (Small Duckbill Nozzle) for Fish Tank by Jeanne Muse

I gave this three stars because it is unique in that it is a moderately large diameter flexible return hose and no one else offers exactly what it does. I intended to use it as a direct connection to the return pipe from my canister filter and loop it up and over the tank wall and then down to the water level and then a few inches above the water. Unfortunately, every link in this tube leaks, A LOT. Within an hour I had at least a gallon of water on the floor. I was forced to use it as in the picture; Look closely and you will see water dripping from some of the joints. So this tube can fit you according to your needs, but definitely NOT outside the tank.
