Uniclife UL400 Submersible Water Pump, 400 GPH Aquarium/Hydroponic/Fish Tank/Fountain/Pond/Statuary with 6' UL Listed Power Cord

The media could not be loaded. I used this pump to help make a Halloween decoration floating cauldron and it was PERFECT!

I dropped 1 star for Noise Level , It is fairly quiet but noticeable.. more of just a hum which is acceptable to me.. but not totally whisper quiet.I have it in a 75gal tank using it to pump water up about 3ft and into a 5 gallon diy canister filter. I have it turned all the way up and connected to 5/8" hose and it cleared my murky tank up in about 2 days.. ( my previous $300 name brand canister filter pump failed and I procrastinated for several months.. so water looked like dank pond water.. couldnt see in the tank.. making it spooky to feed this 15pound dinosaur.. ( snapper ) I will be happy if it lasts over 3 months.. because my expensive filter didnt last that long.. so I likely will go DIY from now on.. rather than waste hundreds on fancy filters with expensive replacement components and filter elements.. I could buy one of these for every month of the year and still not spend as much as the average canister filter setup..

The Good: It has a reasonably long power cord. It's lightweight. It pumps even partially dry and has no issues getting a flow started even uphill through 10 feet of hose. It came with two different size attachment barbs so finding hose was easy.The Bad: It's not as powerful as you'd think it was with a 400GPH rating. While it does seem to have a good head height it doesn't have a ton of power beyond 4 feet high, so upsize if you're expecting to actually go anywhere near the head height.The Indifferent: It's a little noisy due to vibration, and the suction cups on the bottom can alternatively either not hold at all or hold with the power of a thousand suns. The power cord probably should have been twice as long as it is but that's just nitpicking.I use this as an aquarium water transfer tool, and it works great in that capacity, draining buckets down to a water level of half the unit's height (~1.5") with no issues, but I would recommend the next size up due to slow flow if pumping upwards--it can take several minutes to empty 10 gallons into a tank with a pump height of 5 feet.

Still working great

It came broken and so I bought a piece to fix it and once I finally got it set up it’s really weak and can’t pump water three feet in the air for my fountain. Sad but I returned it and got my money back.

Running a phosban reactor with this pump. I have a 29 gallon biocube and phosban reactor is 3.5 feet below it on the floor. This pump has enough power to put the water through the reactor and stir the media well which is what you need to run a reactor. I am able to choke the pump flow down with a ball valve and still stir the media while have another 25% of flow left should I need it. This is a small pump that fits perfectly with my biocube circulation pump in the pump chamber. Just raise the amount of water leve to the max line and both pumps work without any issues. Does what I needed with a cheap price tag. It's a win/win!!! Oh and it also has both a 1/2 and 3/4 barb fitting included. Score!!!!

This pump runs quiet and efficiently takes care of the task I bought it for! (Return pump for a small sump filter). If I was planning to use this to pump pre-prepped water into my aquariums, I'd be rather limited with the cord length, but I have an old sunterra pump for that job with about a 20 foot long cord, so I'm ok on that. Just something to keep in mind when you order, the cord is about 6' or so. (Honestly, that sunterra pump is the only one I have seen/bought with a nice long cord on it..)

For my uses of this pump it wasn't strong enough. I was using it for cooling my wort after brewing using copper chill tubes. It just did not have enough power to push the water through the tubes and recycle it back into the chilled water I had. Using it for this purpose, I would recommend getting one with a flow rate of 800gph or higher (the 800gph I also got still struggles a bit). Having said that, the pump works as advertised.Oh yeah, don't use this with anything higher than 110v. I completely forgot I wasn't in the USA and plugged it into the 220v where I live and the unit was smoking in the matter of minutes. But hey, that is user error 100%
