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 a great air pump. It’s quiet, powerful and comes on automatically during a power failure.

I don’t have to worry about losing my fish if the power goes out!! Which is what actually happened during the night about a month ago. The only thing that was on in the house were the air pumps on my aquarium. Worked perfectly for over 5 hours!

Such a great value for a pump and peace of mind!

The 2 I have have been good. When I did have a small issue it was remedied immediately! If your power goes out they are a must have.

I have the dual outlet pump running four 20 gallon tanks, one sponge filter in each. I have it above the tanks so no check valves, and it runs them on the lowest power setting. I consider it a very quiet pump, but not silent.

I have two 210 gallon aquarium. These pumps are super quiet and very strong. They will reach to the bottom of a 30 inch tall tank sitting on top of a 36 inch tall stand with plenty of power. I bought these in case the power goes out, they plug-in and work like a regular air pump, but when the electricity stops, they have a battery that automatically kicks in and will keep the oxygen level in your tank up, giving you plenty of time Hours to help rescue your fish I’ve tried several other options. These pumps are the best. I forgot to mention that you can regulate how strong the pump is with two buttons you can increase or decrease the flow of air right from the pump without adding a valve as with any air pump you should not operate this without a check valve to prevent any water Traveling back towards the pump. I have also placed one of these pumps on my 75 gallon tank and one on my 45 gallon cube tank

I have both the single outlet and dual outlet Aquarium Co-Op battery backup air pumps. I love them! Our power goes out several times a year. Before I had them I would worry because I wrap my tanks to keep the heat in and also use the heat packs under the blankets if it is winter and the power is out. Now even when the power goes out in winter I don't have to worry about anything but heat. I can recharge them when we run the generator during the day. I have also cut a piece of coarse sponge pad to use as a vibration damper. One is on my desk. All air pumps vibrate so that helps. I can still hear it but I can't feel the vibration through the keyboard nearly as much. I also love that I can adjust the air output on the pump. Plus the black just fades into the background. I need to get more!

Worked like a champ! Powered both my filters for about 8 hours when the power went out. I have no reason to think it wouldn't have kept going had I needed it - but, fortunately the power came back on. Thanks ACO

I really appreciate how the ACO air pump has been engineered to be so versatile and reliable. It's very intentionally designed, and high quality. Customer service at ACO is top notch, and the company's philosophy and products are the industry gold standard for good reason. ACO walks with a purpose.
