AquaMiracle Aquarium Air Pump Super Quiet Fish Tank Air Pump Aquarium Bubbler Hydroponics Air Pump Oxygen Pump Pond Aerator for 80-250 Gallon Water

Very powerful works on all my stones it's a little bit too loud but it's great I definitely recommend it.

The media could not be loaded.  Instead of using the filter al the time I ordered this to provide oxygen and movement for my Oranda goldfish. It’s used outside and it has held up through falll and a harsh winter!My fish love it.No regrets here!

When its on you can barley tell, the most subtle vibration it gives off isnt even noticable. Other than the the air speed is great for my 30 gallon tank

The media could not be loaded.  Very easy setup, instructions are clear. You can adjust every stone for airflow and theres another knob on the pump to push even more air if needed.

Update the vendor gave me some options to fix my issue. This pump is good and I may have gotten a bad pump. But it does move a lot of air and provides enough items to build a small system with enough house to use with a 55 gal.The pump can move a lot of air but damn is it loud and heats up. If put this in a cabinet and the area heated up and made more noise.

I love the fact that this pump has 4 air stones that I placed in 4 spots within my 80 gallon tank. It gives plenty of air to the fish and doesn't give off a lot of noise. I thought, for the size of the tank, that I would have to run the pump full open but after looking at the tank I turned the air halfway down and it was perfect.

shipping was fast and it works very well

Didn't work when I plugged it in. Care quality control.
