Aquarium Co-Op Air Pump with Battery Backup

This is a great, quiet product for your fish tanks. While personally use this product sparingly since I have a larger fish room which requires a larger air pump. However, I have used this product for smaller fry tanks and as an air pump for summer tubs outside (housed inside a waterproof box). I found this product to be quiet and works as expected. I am especially impressed with the battery backup features and Power Save mode (cycles on and off every 15 seconds). These are a great insurance policy in case of a power outage! Highly recommend!

This is by far one of the best pumps on the market. It has a power button so you don’t need to unplug it if you don’t need to run the pump all day, and it has more settings than other pumps as well. The intermittent setting and variable air settings are really good. Very quiet on the lowest setting as well which is good for my Betta.

I have the both the single out put and the double.
They are very quiet and better quality than any I have bought from local pet stores.
That goes for everything I have purchased from Aquarium Co-Op.
Prices are great, shipping is always super fast and the packaging is very well done.

The first two pumps I bought I really liked. They seem to wear out though after two years of continuous use. Also, learned the hard way that they are not water resistant at all. One of mine got splashed and a drop of water made it on to the circuit board inside and killed the power supply. I bought this one to replace the water damaged one, but seems to be some quality issues now. It was very noisy out of the box, the magnet was buzzing against the coil inside the unit due to poor alignment. I was able to steal the magnet/diaphragm assembly portion of the pump from my old one and put it in the new one to get the nice silent yet functional operation back. My second dual air pump is losing it's air pumping power now that it's about 2 years old. It'd be cool if I could buy the replacement rubber diaphragms for these to resolve that problem. Otherwise they work great, power outages are seamless with these.

I live in Chihuahua, Mex. so sadly there is no Aquarium Co-op, so I had to try 5 different brands of air pumps but they were all extremely noisy. Luckily I started ordering my products from Aquarium Co-op to El Paso, Tx. and although it is complicated, it is worth it. The air pumps are extremely silent and during blackouts I feel extremely calm because my aquariums continue to work as if nothing was happening. Shipping was also fast and they arrived in perfect condition. I love love love Aquarium Co-op

Works decent but the power output seems low and the cord did not last very long before a new one was needed honestly we jus kept bc of the fact it's portable

Works great and is super quiet

i’ve got this pump in a 2.5 gallon nano tank with some shrimp and i really love it. it’s super great and give off a good amount for airflow. i have had it hooked up to both a air stone and sponge filter and it works great for both

Several years ago I purchased two single outlet air pumps and they are still working strong to this day. They make very little noise. I can only hear the bobbles in the tank. I recently purchased the dual out air pump, thinking that it would work similarly. The Db rating would suggest that it works the same. Not true. It sounds like a broken washing machine and I can hear it from the other room. I seems to pump the air properly, but at a loud cost. I would suggest sticking with the single pump, unless they have changed the way they have manufactured the units, if you want a quieter system.

Mostly good for the peace of mind that it’ll continue to run in a power outage. I expected it to be a lot quieter though. I can hear it humming through my cabinet even when placed on a 4” foam pad. I switched back to my quiet HOB, but will keep this for my hospital tank.
