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!

I really really really wanted to like this product! My only complaint is that the flow is weak. Overall it’s a good product, just not quite there yet.

I've been looking for something like this for a long time. When I saw that Aquarium Co-Op sells them, I grabbed one right away. Works wonderful!! Fast shipping too! Highly recommended. I have been very satisfied with ALL of my purchases from this store.

This is a great product. Hooked up a sponge filter and an airstone, which are working great in my 40 gallon freshwater tank. Easy to set up and use.

I’ll admit it’s not the quietest air pump I’ve ever had, but I love the battery backup feature. Recently purchased for another setup (not done yet) but got to use it today with a several hour power outage to help temporarily get air to another tank. Great little pump.

I love these air pumps! They really do work in deep tanks, even on the lowest setting. I've only had 1 opportunity to test the battery run time. The power was off for at least 5 hours. I had left it on the highest setting, and it was still running strong

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
