DC 12V Submersible Clear Water Pump, Adjustable Power, 210 GPH Aquarium Fountain Pumps

Bought this to install in my kids water table to keep the water flowing without having to manually pour it in the top for it to flow out the fountain holes. Works great! No complaints whatsoever.

I was looking for a not-so-powerful small water pump for a table top hydroponics NFT build. I had already made one system with a larger, more expensive pump that works well, but I thought this pump with a variable speed option, and cheaper, would be worth trying.It only has to lift water a few inches, so head pressure wasn't really important. I was hoping I could slow it down with the buttons on the pump. Well, when you power it up, it starts at it's lowest speed and can only go faster from there - the low speed was plenty. As you can see from the photo I attached, the 1/2 inch loop has a 1/4" barb coming off it with a valve attached for additional bleed off.Be aware, this pump does not come with a power supply. If you have an extra 12 volt output wall wart laying around from some abandoned electronic gadget, then fine. Other wise you're going to need to get an extra one.This small pump, on it's lowest speed is much louder than the large pump I have in the other NFT grow system. It, 'buzzes'? a bit. It seems to have gotten quieter over the last few weeks or I've just gotten used to it, but still...So far it's working fine for this project. And for the price, it's worth using until it goes out. Also, the outlet side is threaded so I could put a screw-on 90 degree fitting that adapted to 1/2" flex tubing. Not all pumps of this size can adapt right to 1/2 inch tube rather go to 3/8 inch tube, which is harder to find.

I use these pumps as boosters for my tank canister filter. They run 24/7 and have been now for 5 months now without any problems. Very easy to clean. One 12 volt power supply powers both pumps. These are a perfect add on as boosters because you never get the rated GPH as advertised so these pumps bring that GPH up to what the filter should be rated.Totally recommend very well built.

They don't last more than 6 months

Very weak pump. Doesn’t pull water at all.

Use mine with a homemade shower system I use camping on my Harley-Davidson really small and strong pushes plenty of water for showering.

I am using this pump for my hydroponics towers that I 3D print. This pump has been great and the adjustment is really nice to get the right amount of flow depending on the tower height.

No 12 volt DC plug to plug it in to make it work so that's pretty worthless although the description doesn't say it has one but how you supposed to plug it in
