"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. Considering the warranty and performance, I upgraded my rating by 2 stars.

Eheim 720686370043 First Impressions

"Very quiet and powerful."

Provides proper wattage for all my accessories. A simple piece of foam under the unit solved that. Overall seems like a good air pump. Otherwise, I would buy another one. For a solid working, quiet pump, this is about as good as it gets. The pump works well when there is no defects. The pressure isn't as great as I hoped.

Eheim 720686370043 Final Thoughts

"5 gallon Betta tank."

I had the Whisper models and they were way too high in emissions. The pump works well when there is no defects. The added tubing and manifold make this an even better value. If it craps out anytime soon, I'll update the review. Provides proper wattage for all my accessories. The rubber feet dampen most anything that the sealed pump doesn't cover. The pump is so powerful that it pushed off the connection tube several times.

Tetra 75077877 First Impressions

"It is good and quiet."

The new unit works fine as a secondary air pump in a 75 gallon fresh water aquarium. The current from the bubble wand is softer but its still a current. I like these, great deal for the price. So I completely disassembled the sponge holder. Make sure the hose is connected well. After 3 weeks, I received a new one in the mail. Push once for On and hold down for 5 seconds for off.

"Definitely reccomend!"

Super quiet, lots of power and looks super sleek. Yes it obviously makes some noise-but not at all as much as I was anticipating. For now, I'd say I would gladly buy another. The motor was working but air was not moving. I was currently using 2 Whispers and they were anything but whispering. But this one has no noticeable sounds. I'm sure it would run a much larger bubble stick also.

5. Hagen Marina Air Pump

Marina 11110 First Impressions

"I hope this helps anyone."

Apparently the dome shape plays a significant role in noise reduction. Use large Air Stone Bars for giant columns of air bubbles. This is actually the second one I have purchased. You'd think this thing would stop working, but it didn’t! I use them in my Tilapia tanks and Koi pond. I currently have it in a closet to grow aquatic plants and brine shrimp. I will just keep the old one for parts should I need it.

"It is so clean."

And one to the additional accessories for extra oxygen output only. After 3 weeks, I received a new one in the mail. I have to put my head behind the tank to hear it! I was going to buy 3 small air pumps to power 9 sponge filters when I saw this pump. It just sounds like a large freezer. The pump works very well in my 75G tank. Ordered this air pump to replace one of my other pumps and the difference is amazing.

"So does this one!"

Danner, Fusion, Eheim are adjustable. The company made it right and took care of me. It really is pretty quiet- once you unclog the air pathway. It still works internally, but no air. I guarantee the fan will help it's shelf life. Highly recommend if you desire HIGH air output on several tubing lines! The current from the bubble wand is softer but its still a current.

"It is perfect!"

I currently have it in a closet to grow aquatic plants and brine shrimp. You MUST use a fan with this pump or it will def burn out or lose pressure. Its not going to vibrant on anything! I have one running to sponge filters in a tank and it pushing a nice air flow. I really am impressed with this air pump! I'm using it for small start-up hydroponic system. Ordered this air pump to replace one of my other pumps and the difference is amazing.

"Wish didn't have to."

I use them in my Tilapia tanks and Koi pond. I'm not going to knock the product for my own paranoia though. This one is far better than I anticipated! They generate a TON of air and last a long long time. I honestly wasn't expecting that much of a difference but man was I surprised. And check the filter often, at least every two- 3 weeks. I put a nice little fan next to mine and it now runs much cooler!

For a solid working, quiet pump, this is about as good as it gets. 5 Watts, Fusion 700 rated at 6 watts,Whisper 300 rated at 7. I had to use valves to reduce the output. Super quiet, lots of power and looks super sleek. And there are fixes around all of it. Larger tank owners won't have my issues. The company made it right and took care of me.

"It's easy to set up."

I started to write a poor review of the pump. The air being pumped out can be quite warm as well. It makes the perfect size bubbles and the fish love it.
