These blow good and hard, good for deep tanks, some last for years, others die in about a year. I have a tank maintenance. service so I use a lot of these every year. You can pay a lot more but none are any better. Some of the piston pump last longer but a lot louder. Bob

I purchased this Million Air 600 Air Pump for 2 of my 3 aquariums. This pump is powerful, has an adjustable air flow and 2 outlets for connections to 2 aquariums. I highly recommend this air pump if you have 2 aquariums that you would like to aerate from one pump. Thanks a million!

I've been buying those weak pumps you find at pet stores for years. No more ! This pump is incredibly strong. Best pump I've ever purchased, and it cost half what those large pumps cost at stores. Very very satisfied

This seems to be a good pump. I took it apart and looked inside and it seems to be well built. They could have made it dule voltage as i need some 120 and others 220 VAC.
