Aquarium Air Pump Chialstar Quietest Super Energy Saving 1.0W 15 Gallon Aquarium Pump for Fish Tank Oxygen Pump with Air Big Stone and Silicone Air Tube

Mine came in the mail with a minor chip on the bottom of the line where the Stone was attached. I used it for MONTHS and nothing has happened. The suction worked well! The noise it gave off was as minimal as a bubbler is... it produces A LOT of little bubbles and definitely provides oxygen in the tank. The only downfall was... my suction cup wouldn’t stick long so I ended up tanking it to the tank... this did nothing to the pump.

It's been a great addition to my 5.5 gallon, glass fish tank. It's extremely quiet and it was very easy to setup. Because of the way I setup my fish tank area, it's out of the way, yet easily accessible and I'm able to see if something's wrong with it or the tubing. I didn't think I'd need one for such a small fish tank but it's really helping out my filter by circulating the water from the opposite end. Adding live plants or shrimp is now more of a possibility. I'm impressed and happy with it and my fish has been investigating it and he doesn't seem too upset with the change in the water circulation. Great quality, I recommend it!

So I like the pump, it's actually really quiet. The bubbles are louder than the pump. I am using it for hydroponics in my 2.6L Aerogarden Harvest tank to supply extra oxygen to my plant roots.Pros:- quiet- good for a very small tank- low wattageCons:- the suction cup on the back of the pump already fell off my tank a few times (installed today), it doesn't seem too strong. We'll see how it goes. EDIT: I wiped the suction cup with some water and applied it again, and now it's sticking good. Something about the water helps it stick.- my kit didn't come with an air stone. good thing I had one on hand, but the seller should have better quality control.Summary: If it weren't for the missing air stone I would have given 5 stars but can't give 5 when it's missing parts.

I finally found a quiet pump! I work at home and I have a beta tank next to my desk. The pump I was using was quite loud and although I could ignore it most of the time, when I did pay attention, it annoyed me. This little pump is super quiet. The stone is a bit large, so I may opt to purchase a smaller one since my tank is not that big. My Beta "Val" was hiding and didn't want to be put on Amazon, but I know he will love the silence as well. I would recommend this if you have a tank at least 1 gallon and up.

Works well after a few months. Not terribly quiet but for the price and size it gets 5 stars.

Love this cute air pump! Small size,but powerful enough for my fish tank! It is very quiet and no noise of vibration! Awesome!

This is a great low energy air pump. It works fantastically with a small sponge filter. However, I tried to use it with a corner filter, a small one with sponge and charcoal. With the corner filter this pump definitely got loud on occasion. I would say the noise coming from it tended to fluctuate. I noticed most of the noise from it was carrying through the bubbles/water. The machine itself isn’t that loud, but they bubbles kindof amplify whatever fluctuations are happening in the air output. I’m super sensitive to changing noise/ a light sleeper, and there were nights where I wanted to unplug the thing. I finally switched it with a noisier but constant air filter. Then I tried it with a sponge only, and it was much better.

It's small and it works, but it isn't that quiet. Maybe I got a bad one?
