Hygger 660 GPH Submersible Aquarium Water Pump - Black Metal, Ideal for Fish Tank, Pond, Fountain & Hydroponic Systems

Nice little pump. I’m using it for water changes and does the job well

I've only used it once, and let me tell you. I did a 25% water change, start to finsh, in my 29 gallon aquarium, in less than 10 minutes! BIG back AND time saver! I tried the model a step below this one (~150gph?) Which worked OK but it was too slow for me and I have a tall tank so it struggled to pump the water up to where I needed it. So i tried a different brand at 800gph... WAYYYY to much. But this 400gph model is just write! And seems to be built well. Pair with python "the hook" and some 3/4 id silicon tubing and you're set! Would highly recommend 👌

Haven't tried the pump yet but dont buy any of the "suggested" hose sizes, it auggesed a 5/8 ID 1/2 and none of the hose barbs with the pump fit it, the hose will actually fit inside the hose barb. Update 11/29 Works well so far after three water changes, will advise to throw some teflon tape on the barb that works best, it leaked a little at first and after trying a o-ring so tape it was . I have a extra fluval hose for the 7 series pumps and the rubber ends made a great seal on the barb and easily removed for storage. Takes up minimal space and water changes to and from buckets are a breeze. Will buy again if anything happens.

I have both the 215 GPH and 400 GPH models. My use is for pumping new water into an aquarium. It is also useful if you need to quickly remove water from an aquarium, but I prefer using a siphon vacuum for draining. I recently bought a 10 gallon aquarium and found that the 400 GPH model was too strong and caused the substrate to be disturbed. The smaller 215 GPH model is weaker and works great for the smaller aquarium. I don't have any complaints about the 400 GPH model, but for the 200 GPH model the included 1/2" barb fitting is slightly smaller than 1/2". That causes 1/2" ID tubing to not fit snug, and the hose blows off in use. I see two other reviewers who noted the same issue. I've had no issues with the other fittings, and it seems to be an issue limited to the 1/2" fitting with the 200 GPH model.

Exactly what I was looking for. Quiet and pulls up Debris and fecal into the column. Doesn’t stop if big debris goes inside pump keeps going. Super quiet! The Others I bought were too loud for my 180 gallon. No too strong either. Perfect product !

This thing has failed me by August. Literally a 6mo use. I have unplugged it and switched sockets multiple times. This thing was not built to last long. Very disappointing, as I was injured in June and have grown to rely on this thing for water changes as I am unable to walk. Purchased it in February and it's quit working already. I read that mised reviews on Hygger products and this thing has let me down when I needed it most. I filled my bucket with waste water and plugged this thing in, and it just sat submerged in dark water🤢. I was so disappointed. Took it apart, and removed magnetic impeller. I will update when I try again this week of it works but so far, huge let down. Don't waste your money unless you just need this for a month or two.

Buenísima, este producto es para multi-uso puedes hasta regar el jardín con la fueras que tiene le puedes poner hasta una manguera larga

It's very small which is great for smaller tanks but it's also not that powerful which may be great for smaller fish or shrimps. Despite that we use the netting from a breeding box to make sure they don't get sucked through so I wish I went more powerful in the end since my sink hose sucks at about the same rate or even faster, but generally not fast enough to warrant the price. I would rate the suction as acceptable but I will buy a more powerful one in the future. In this case I am talking about the 215GPH that I bought. I actually connected this to my sink siphon which is really convenient and I recommend. That way I can plug it in to take water out and unplug it and start the filling with the sink siphon to fill my tank, no need to take the water pump off which is convenient. This is easier to siphon out than a hose cause you just plug it in to get started. Overall, I would recommend getting a more powerful one with one of those breeding box nets, put the net over the device to stop shrimps and fry from getting taken away. Attaching to a sink siphon with the 5/8" is possible so do that if you have one.
