Review on KEDSUM 330GPH Ultra Quiet Submersible Pump With High Lift And Grounded Power Cord - Ideal For Fish Tanks, Ponds, Aquariums, Statuary, Hydroponics - Includes 3 Nozzles And 1500L/H Water Flow by Darren Anderson

Powerful pump. I have it in my 100 gallon pond houses in a filtration rectangular container. My pond is not built in, it is a patio pond that I buried in the ground. Pumps the waterfall up 2.5-3.5 feet and makes my waterfall look amazing. Even flow and strong. The only reasons I am giving 4 stars is because it seems to have a strong vibration, that I can feel in the water whenever I stick my hand in it and when I am touching my pond container. I hope it doesn't stress out my fish too much.
