Odd thread size
Fantastic pump! Plenty of power and extremely quiet. Time will tell but so far great value. Love the variable speeds and digital display. Have it running submerged in my sump pushes plenty of water straight up 5â through 1â PVC. 300 gallons per hour on setting 7.Odd thread size though. Thereâs no fitting out there at your local hardware store that will fit it. Not a problem if you use hose or tubing but I wanted to hard plumb it into my existing system. Had to get creative. Used the large hose barb fitting it came with and glued that into the pipe. Works great.

Superior flow and super quiet
So far so good. A dc pump makes all the difference in terms of controllability and electricity use. Plenty of power for my 75 gallon saltwater tank.

Quiet, cute and strong
The negatives (only a few but not bad):1). There should be a 90 degree angle input option that can be screwed on so that it can work in lower water levels.2). The remote should have an on/off, not just a 10 minute “feed” shutoff option. I ended up buying https://www.amazon.com/gp/product/B01FT4RBBM/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1 to turn the pump on and off.3) One set of plugs is not screw in, and they tend to fall out or get pulled out and of course the pump won’t work.4) I make fountains and I know there are many people who will use these for other than fishtanks. So perhaps the word “FEED” can be replaced by the word “PAUSE” so that people can use it on fountains, in water walls and other places besides fishtanks.As I said, these are mainly all minor… This is a really great pump.The positives:It’s great! It’s so quiet. Even on the level 20. I like that it goes up 20 levels. Many pumps go up to 3, 5, 10.It pumps the amount that they said it does.I also like that it’s white and black, which matches the fountains I produce.The connection design and the pieces that go with them are good, strong and solid.I have tried mostly every pump on Amazon. This is clearly top for me and I plan to buy more.I plan to buy many more.

No noise! Plenty of power!
Great pump! Use it for my hydroponic RDWC a day couldn’t be happier. Completely silent, great flow, and very versatile. Came with plenty of adapters so fit whatever hose you might use. I’m using it fully submerged. I didn’t know if it had turned on until I felt the pump hose and felt slight vibration from water flow. It has options for aquarium applications and various pump settings to adjust flow and tempo. All in all a great unit at a good price.

Super quiet and easy to use
I actually use this pump to pump water from my water station into my aquarium with the inline function. I do this because I am able to get almost all the water out by aiming the inline tube towards the bottom of the brute garbage can. The controller works great for turning it on and off when I’m done too. When I first tried using this pump with the inline function I thought it was broken because it wasn’t pumping water through the tube. I soon figured out that you need to prime the pump and fully submerge the inline tube in water to get good suction. Also, it will make a loud buzzing sound in the beginning of pumping but once all the bubbles are out it is dead silent. Probably the quietest pump I’ve ever had.

Not sure yet
It is running and I love how silent it runs and that you can regulate the flow. Way better than an AC pump. However, it intermediately makes a high pitched noise after only two weeks. We will see if it lasts. My guess is no.

Very quiet. Saved my fountain from the trash.
In early 2020 I purchased a fountain because we were going to be spending more time in the garden instead of traveling. I wanted something soothing and something that the birds can use to drink from during our hot summers. The fountain is made of metal, it’s beautiful, modern, and lovely to look at, but for just about a year it has been nothing less than a pain and this was only due to the vibration from the pump and its amplification through the metal body. I was ready to scrap it and say goodby to $2,000 after a year. I went through 5 different other pumps and all had the same issue. Then I made one more search and came upon this pump. As I installed it, turned it on, and waited, I was in awe at how quiet and vibration-free it was. Actually, I was speechless. Finally, the fountain that was to be soothing and beautiful is just that. Great product, great value and it is quiet: virtually silent. I’m happy.

I used this pump for almost a month now, it is so quiet compared with the 2 other pumps I have purchased before, even those 2 other pumps were also advertised they are quiet products.I have a 200-gallon fish tank set up in my living room, the sump pump is below my fish tank inside the cabinet. The environment is really quiet. After I use this DC-4000 pump, I can’t even hear the pump is working, all I can hear is the water running.When I first install it, the pump was set to pulse pumping mode, without the user manual, I can not figure out how to change it to the proper setting. Those setting does not make sense by just look at the controller display. After I read the manual and programmed it to the setting I want, it works perfectly.From time to time, I turn off the power to do the water change, the setting will remain after I power it back on.Overall, just need to read the manual, program to the setting you want, then it works perfectly.I totally recommend it to other users.
