"Looks good."

The pump works very well in my 75G tank. This would be the fourth attempt to satisfy my needs and my ears. I have 3 of them on different surfaces. The company made it right and took care of me. The pump is so powerful that it pushed off the connection tube several times. I hung it so its not touching anything. I'd say this pump would be loud if it were used in the same room as you.

CNZ ACO002 Final Thoughts

"I can't hear them at all."

Yes it obviously makes some noise-but not at all as much as I was anticipating. The stone is very heavy, so it is easy to position and stays put where you want it. Considering the warranty and performance, I upgraded my rating by 2 stars. For the money, this air pump cannot be beat. It still works internally, but no air. I set up 2 more and still all the control valve are not open 100%. I'm not going to knock the product for my own paranoia though.

"It is good and quiet."

I hung it so its not touching anything. We can hear the tank bubbles, but nothing noisy from the pumps at all. It really is pretty quiet- once you unclog the air pathway. The pump works very well in my 75G tank. I did notice that it tends to run very loudly and hot. Yes it obviously makes some noise-but not at all as much as I was anticipating. Danner, Fusion, Eheim are adjustable.

"It is perfect!"

It didn't blow air out that line, while it still had a little water in the unit! This would be the fourth attempt to satisfy my needs and my ears. Pay a bit more but the quality is worth it. I'm not going to knock the product for my own paranoia though. I own Whisper 10, 150, 300, Eheim 400, and Fusion 700. My 20H tank is in my office, 3 feet away from my desk.

"Wish didn't have to."

For a solid working, quiet pump, this is about as good as it gets. The pump works well when there is no defects. Provides proper wattage for all my accessories. Great Product, BUT, its noisy and vibrates like mad on its rubber feet. I have this in our small aquarium with an LED bubble stone. The rubber bottom feet really help to keep the unit quite and in one place. Works well in my 75 gal tank running a 36 inch bubble stick!

Carefree Fish Lithium2 Final Thoughts

"Don't buy the Whisper 10!"

I knew I had to try something else. I use them in my Tilapia tanks and Koi pond. This is actually the second one I have purchased. I have to unplug it every time I want to shut it off. It pumps out enough air to keep millions of air bubbles going in this 200g+ Aquarium! I'm not going to knock the product for my own paranoia though. It has one air outlet so i used a spliter& ran a tube to each end of bubbler.

And one to the additional accessories for extra oxygen output only. It makes the perfect size bubbles and the fish love it. Works well in my 75 gal tank running a 36 inch bubble stick! Overall seems like a good air pump. Otherwise, I would buy another one. My 20H tank is in my office, 3 feet away from my desk. I had the Whisper models and they were way too high in emissions.

This seems to be a good little pump that really puts out some air! Don't be startled if you test it without oxygen tubes, It is Very noisy! The reviews sold me on this product but I was still skeptical​.

Push once for On and hold down for 5 seconds for off. I keep the pump and air valves in the box to lessen the noise. This seems to be a good little pump that really puts out some air!

"Be advised!"

We can hear the tank bubbles, but nothing noisy from the pumps at all. Almost all people will be highly satisfied with this unit. The pressure isn't as great as I hoped. Highly recommend if you desire HIGH air output on several tubing lines! Otherwise, I would buy another one. Adjustable air flow settings which is new to me on a air pump but very convenient. I set up 2 more and still all the control valve are not open 100%.

"This is plenty of air."

I have an undergravel filter and a few other accessories that push air too. So I completely disassembled the sponge holder. It didn't blow air out that line, while it still had a little water in the unit! I have been in the hobby for 20+ years and this is the best air pump! This runs pretty darn quiet for a high output air pump. But if it's in another room, it’s not bad at all. Its not going to vibrant on anything!

Use large Air Stone Bars for giant columns of air bubbles. I was wrong it has enough power to run all 9 with air to spare. I guarantee the fan will help it's shelf life.
