Review on Powerful And Quiet Submersible Pump For Aquarium, Pond, And Hydroponics: KEDSUM 660GPH Pump With 6Ft High Lift And 3 Nozzles by James Cabot

I purchased the 550gph version in July of 2017. I think that is a decent pump compared to other pumps. but compared to other cheap pumps this one is pretty darn good!I use this to provide water to my refugium- which runs independently of the rest of my sump. The water flows down from the display, gets filtered through the skimmer, then flows to the center chamber. In the center chamber is two pumps. My return line and this pump. This pump lifts the water 8 inches and then splits two ways and feeds the fuge. the water then overflows back into the center chamber.I think this pump would be insufficient to do anything but this use. The pump is too large to put in the display, and too low on power to make the climb to pump as a return line.As far as noise. This pump is medium level. You have to suction the feet just right, and in the right place on the glass to reduce the noise. Not as loud as a pond pump from home depot. not as quiet as a name brand return pump. But, nothing is louder than my skimmer, so as soon as it turns back on after a feeding, this pumps noise is irrelevant. If this was the only thing running, you would notice.I have used this in the past to pump fresh saltwater water from a large container to the tank and couldn't see that flow being enough to use for much else. But, sometimes you don't need super pressure, you just need something handy to do a small task. I have ordered the largest version of this pump to use for this purpose, and thought enough time has passed to give my opinion on this one. But the fact that i have ordered another should tell you how I feel about it. :)
