Review: Great for 55 to 75 gallon tanks! - Have had this pump for close to a year now. I run two airstones and keep it on max output. That being said I've had ZERO issues and this thing is very quiet for the amount of bubbles it produces.
Review: Quietest pump I’ve had—out of dozens - At one point in my life, I had 8 aquariums in my apartment—nuts about the hobby. I cut down quite a bit because my new obsession is houseplants; I have 3 now in my living room. When my friend offered me a free axolotl baby, I couldn’t resist. The main reason I haven’t allowed plants and fish/other animals to take over my bedroom is because that is my quiet and dark cave for when I sleep (I work at home nights, and so with a chronic disease, I have to sleep a lot during the day). Well, axolotls are great because they require no heater or light (they live in cold mountain streams that are murky), but they do need filtration and good oxygenation. I have gone through a lot of air pumps in my life that eventually got problems with the rubber mufflers and then the vibration could drive you mad. This one has been great. We barely hear the motor at all, only the bubbles, as in the video. Somebody in another review complaint that it wasn’t even enough to power the devices for a 20 gallon tank, and I don’t understand that because I have a 20 gallon tank (a high one, too) and both a bubbler and a sponge filter. I love the adjustment knob, but I have the knob turned all the way to the lowest setting and it’s powerful enough for both. Maybe that person is using an air bubble wand that is too long or has a clog? At any rate, it has not been my experience at all and I love this. I can compare it to maybe 20 pumps that I have gone through in the past. It has been quieter than all of them so far, although I cannot speak to longevity… I have only been cycling the tank for two weeks so far. I’m definitely a fan now and I’m thinking of buying a second one.

## Questions & Answers

**Q: Does this air pump be able to use just one outlet?**
A: I would say yes, if you mean one air hose bubbler.  I have mine with 2 tubes connecting to a 2 to 1 T splitter to one hose and it works great.

**Q: What size is the airline tubing?**
A: Any type standard airline tubing made for aquariums will work well. Available from Amazon or your local pet stores.

**Q: Does this come with all the tubes?**
A: It has only one aquarium air pump, but it has a large air volume.

**Q: With two places to put air tubing do you have to use them both?  Can it be left the way it is?**
A: You can use one air outlet. That's what I'm currently doing.
