Review on Boxtech Super Quiet Aquarium Air Pump - Long-Term Quietness, Adjustable Air Volume & Oxygen Pump for 1-150 Gallon Fish Tanks by Jennifer Corbett

I only have a 5 gallon tank so this will work perfectly. It has 2 air outlets and an adjustment dial to adjust how much air you need or need in the tank. I'd like to test it at high volume, but I can't. He is very quiet! So much so that I'm bending over to see if it's even working. This is a pump only, so it does not include tubing, check valves, or air stones. So keep that in mind when ordering. The air outlets can be used together or individually. When it arrived it was very well packaged and in perfect condition. Honestly I think it's too expensive since it's just a pump. Others are cheaper and go with everything. Some people who are interested in aquariums may already have add-ons, but we're just getting started so we need to buy more things now. I wasn't expecting it to come with extra features, I just said for the price it should be.
