GROWNEER 550GPH Submersible Pump 30W Ultra Quiet Fountain Water Pump, 2000L/H, with 7.2ft High Lift, 3 Nozzles for Aquarium, Fish Tank, Pond, Hydroponics, Statuary Black

Pump was a replacement in a waterfall we got from Home Depot. It works just fine. More gpm is not always better as it can cause excess water to splash out and require more refilling of the waterfall. This pump provides a steady flow with no spillage.

Have not installed this one yet. It is a spare. However I have used two others. The second one is in service now. I use them in an outdoor evap air conditioner. The water around here is so hard I go thru one every year or so. I took the first one out the other day. It was so corroded up it would not run. So I changed out and the new pump puts out enough water to keep my medium wet. Recommended.

Beware of what you are buying this product for and do your research beforehand.I bought this to circulate the water in my 55 gallon Turtle tank without really knowing how powerful these pumps can be and for that reason I am grateful this model allows me to adjust how strong of a current I can get because I not only blew all the tank Deco's clear to the other side of the tank (this includes four large hides and about ten artificial plants) I also flipped my turtle head-over-tail and he landed on a pile of all his hideouts. Anyone that has ever been on the receiving end of a Turtle's dirty look (even though he wasn't hurt anywhere except his pride) knows how painful and degrading it can be.

I used this to clean the heat exchangers in my tankless water heater. It can't handle much head pressure (or back pressure) and it was pretty slow coming of of my water heater, but it worked.

This pump has some power! I tried it in my sink and it shot straight up to my cabinets! So if you're looking for a pump with some power this is it!

The media could not be loaded. I have a 51" fountain I needed a pump replacement for. This is a good pump, but on the lowest setting had too much lift for what I needed. When I ordered, I figured I would turn it down low then it wouldn't have to work so hard - but still way too much power and overflowed my fountain. Turning it down to the lowest setting also made it vibrate more. There is no doubt that if you needed 7.5ft of lift as it's rated - it will easily do it. I'm going to go down to a smaller pump as I need about 4.5ft of lift.

I have an outdoor water fountain and from time-to-time I have had to replace the pump. I have consistently replaced it with a GROWNEER 550GPH Submersible Pump 30W Ultra Quiet Fountain Water Pump, 2000L/H, with 7.2ft High Lift, 3 Nozzles for Aquarium, Fish Tank, Pond, Hydroponics, Statuary Black. In past purchases the pump came with a heavy-duty power cord with 3-prong plug. The new pump I ordered ca M e with a light-weight power cord with a 2-prong plug. For an electrical device that is both submersible in water and exposed to the outdoor element, I found this "change" in construction to be very disappointing. The next time I need a new pump, I will shop around for a better cord.

Works good but the adjustment is not as good as I wanted even a lowest flow it still has a lot of flow for the fountain I have.
