Review on GROWNEER 550GPH Submersible Pump - Ultra Quiet Fountain Water Pump, 30W, 2000L/H, with 7.2ft High Lift - Ideal for Aquarium, Fish Tank, Pond, Hydroponics, Statuary - Includes 3 Nozzles by Dana Wilson

Silently pumps large volumes of water. This is a much more powerful pump than many others that cost a little less. Some complain about the height of the jet of water it pumps when used in a fountain, but of course as with all pumps this depends on the diameter of the hose used. The larger the hose diameter, the lower the height. We're talking about the physics of maintaining hydraulic pressure. If you need a high spray, make the tube smaller. Therefore, when you press the discharge end of a garden hose with your thumb, the jet widens. Same deal.
