AQQA Aquarium Air Pump,3.5W 5W Dual Outlet Oxygen Pump with 2 Air Stone,Adjustable Air Valve Quiet Bubbler Pump,Up to 160 Gallon Fish Tank (3.5w)

These are actually quiet as stated. They are also adjustable so you don’t have to have bubbles full blast. Although you could use them full blast if you wished. The only thing - I thought they came with a Y so you didn’t have to use both tubes but they don’t. You will need to purchase a Y or use 2 tubes in your tank. Still recommend!

Very quiet. If you are only using one tube, put painter’s or other tape over the other hole. Quiets right down Output seems adequate. I don’t need it very strong as it’s for newly hatched fry, but I did crank it up for a second and it’s turbulent enough if needed

It's been a few months and it's working like day one I like the fact that I don't need two of these for my two Siamese fighting fish bowls it helps a lot as much simpler it doesn't use a lot of power or electricity and it's not loud it comes with the air tubes and the stones at the end the prices very great I highly recommend this product

Why did you pick this product vs others?:The price was a big factor on purchasing this air pump. There were enough pieces to customize. The only thing I didn't like is the noise level, its kind of loud. Power:The air pump knob works well in adjusting the flow level Pump quality:GreatBuild quality:GreatDurability:Great

Este sistema de bomba de aire funciona muy bien y es imperceptible el sonido, muy práctico en mi pecera de 10 galones, aunque abastece para mas.Lo compraría de nuevo, recomendado.

Why did you pick this product vs others?:The price attracted me and the size. Ad clamed it was a quiet pump which I have to disagree. Fortunately my aquarium is set up in a spair room so thoe noise doesn't disturb my sleep or relaxing in my living room. Provides good air flow for the air stone.

Works great and good price

The media could not be loaded. I absolutely love these air pumps. They’re quiet and effective. I just wish that AQQA made single output air pumps as well. You can easily make a dual output pump into a single by adding a short length of hose to one output and capping it with a flow adjuster set to closed. If you don’t do this, the pump will run loudly. You can see how I set this double pump as a single in my video (the other tank is running a single AQQA pump using both outputs).I have two of these and they’re both very quiet. Just a low hum. I have two Tetra whisper pumps, one is a 20 and the other a 10 and they are both loud in comparison.If you’re looking for a quiet pump just get one of these, even if you only need one output.
