Pawfly Aquarium Battery Air Pump 40 GPH Oxygen Pump for 5 to 30 Gallon Fish Tank Portable Aerator Pump for Outdoor Fishing and Fish Transportation, Battery Not Included (Accessories Inside The Pump)

I recently purchased this bubbler, and I couldn't be happier with its performance. In a real test of endurance, it ran continuously for over 55 hours, and the results were astounding. I needed to keep a dozen shrimp alive in a 5-gallon bucket, and this little device proved to be a true lifesaver.Pros:Exceptional durability: The fact that it ran non-stop for more than two days without any hiccups speaks volumes about its build quality.Efficient oxygenation: My shrimp were as lively as ever, thanks to the steady supply of oxygen provided by this bubbler.Easy to use: Setting it up was a breeze, and it worked flawlessly from the get-go.Compact design: It doesn't take up much space, making it ideal for smaller containers like my 5-gallon bucket.If you're looking for a reliable bubbler to ensure the well-being of your aquatic pets, this is the one to go for. It passed a critical test with flying colors, and I have no doubt it will continue to perform admirably. Highly recommended

It has worked for multiple days without changing the battery. I used it for a 5gal bucket overnight and traveling all day while fishing, then most of a day during a power outage and it's still ready to go. It has enough power to keep my 20, 10, 1, and 2 gal alive all at the same time. I just disconnected my existing tubing from my usual bubbler, connected this one, and adjusted the valves a bit. The bubbling wasn't crazy but it would have kept the tanks alive for a good while.

Works to keep bait fish alive

Battery powered, bought to keep my axolotl alive on a 12hr drive/move. It did its job! It's a bit loud, the humming vibration, but not enough to be a bother. It makes a lot of air bubbles into the water for your aquatics. Batteries kept going for over a week while I got his new tank set up.

Works. Just very loud and it specifically says it would be not loud.

I used it multiple times to aerate a 5 gallon bucket for Brim livewell. Worked perfectly.

This pump saved my fish during hurricane Milton. Two days later without power, it was still going strong with the 2 D batteries. The cover is difficult to pull back, but once open to the battery compartment, you'll find a small hosing line and an air stone. It worked like a charm.

This air pump works well. I had to transport some Koi about 6 hours by car and used this pump to keep their water aerated during the trip. All the fish were fine and this pump paid for itself in one day. Now it is on hand in case of a power failure. I live in a hurricane prone area and there have been times that I have lost power for days. Having this pump means that my fish can survive future storms.I think it is well made and I am very happy that I bought it.
