Hpumps Aquarium Air Pump, Ultra Quiet Oxygen Pump Bubbler for Fish Tank up to 26 Gallon with Air Stone Air Tube

Buyer beware of the device's short life. Initially was happy at the small size and quiet operation, even if it produced little bubbles. Now, after a few months of use it's completely dead, producing no air. Am looking to replace it. Funny but my decade old bubbler that is so much louder, is working stronger than ever as my back-up while I search for a new one.

I ordered the largest model available on Amazon, for "up to 50 gal." What I received was the model number "YDBQ112", which is a smaller unit. If you read the specs of YDBQ112 in the included manual, it states that it's up to 100L. 100 liters equals 26 gallons, NOT 50 gal! There is a model "YDBQ113" which is not the one offered for sale here, and that's the one for up to 200L (52 gal.) which would be the correct pump. The other specs provided here (2 Watts, 600mL flow rate) is for the "112" unit, which is too weak for a 50 gal tank. The "113" unit spec is 3.2W, 1000mL flow rate, and presumably more suitable for a 50 gallon tank, BUT THAT'S NOT THE ONE YOU'LL GET!The model number was not indicated on the box. You'll find it on by the prongs of the AC plug, which is practically impossible to read. You'll need really good eyes or a magnifying glass to make it out.Lastly, the AC plug design is terrible. The prongs are located in the MIDDLE of the plug housing, parallel to the length of the housing, which is about 2" long. In other words, in certain power strips, you may take up 2 or 3 receptacle spaces. Use a short extension cord to overcome this design flaw. You may need an extension cord anyway, because the AC cord attached to the pump is very short--if you plan to attach the pump to the tank glass using the included suction cup, the cord will probably not reach the floor, let alone a wall receptacle or a power strip, if the tank is on a typical stand.Overall, the concept is great, and it is very quiet (maybe because it's so underpowered?), but between the poor plug and cord design, obscured model info and label, and shipping a model that does not match the described capacity, I cannot recommend this pump over a more traditional pump, such as a Tetra Whisper series.

Great little pump, nice and quiet. I had it for a few weeks now, no problems.

good product.

super quiet

This little pump packs a huge punch. I didn't expect it to work as well as it did. It is super simple to set up. I didn't even need to cut the tube to get it to work. I just set up the pump placed it in the water and it works amazingly. I will add photos asap. I received this product for free in exchange for my honest review. All thoughts and opinions are 100% my own.
