20 - 60 Gallon Aquarium Air Pump by Aquaculture

I didn't realize it has 2 separate outputs, each has an impressive amount of flow. I use this for my live bait tank when I'm ashore. just one side produces enough oxygenation to keep a tank (25-100) of live shrimp happy for days if you change out the water daily. Just for fun, I dropped both lines in, it was like a live shrimp Jacuzzi! (minus the mixed drinks)The review asked to rate suction, which isn't accurate, but I get the gist of what they want to know. I'm very pleased with this companies products, and so are the shrimp!

It chose it because reviews said it was very quiet. It is very quiet. Problem in it only lasted 6 months in normal service power 2 filters.

The media could not be loaded.  Fairly quiet, we’ll, its quieter than the little one we got at pet smart.Daughter has one for her large 20 gallon tank, been working for 2+ years, bought little one for sons 15 gallon tank, it was awful. So I searched for the one my daughter had….. Found it!!!It’s great!

I usually don't write reviews but this case it’s a calls for a warning to the other buyers, this pump received a high score, from the moment it was received it barely worked, and also not very quiet, I recommend in every possible way to avoid the purchase of this product. Low quality product and very low performance!

The pump works great and there is equal output of air from both ports. I will definitely order another if I need one.

I set up the pump with 4 stones (6 were advertised) in less than 8in of depth. the pump does not create enough pressure/volume to drive all 4. returning the unit, getting something better

This pump is amazingly quiet and two hookups are great! Buy it :)

Great!
