Fluval A402 Aquarium Air Pump 4.0W

Using this for my 120 gal tank with 3 koi. After turning off my old tetra air pump and replaced it with this, the house instantly got quiet. No buzzing sound at all. Air pumped out very strong and the unit looks solid. Been using it for a week now. Love it.

This is the worse air pump I have ever purchased. The first one I purchased started making this loud noise and I had to return it. This second one I have just stopped working and no longer pumping air in my air stone. It only lasted for 30 days. I am glad I kept my Top Fin air pump because I reconnected it and started working right away. Stay far away from this Fluval A402. It is not worth a broken penny.

Works great👍

Great air pump, but it sometimes has a loud rattling noise that goes away after repositioning it.

Works in my 55 Gallon and barely hear it from inside my stand.

Completely stopped working and started making humming noise, DO NOT RECOMMEND THIS PRODUCT.

It’s pumping air just like it should, but I don’t think that I should have to replace these pumps every few years. While Fluval makes a lot of aquarium components, their long term quality is questionable and quirky. I do keep going back to that brand, though, and they do have a loyal following. My trusted aquarium store only carries their products, so that says something as well.

love how quiet and easy to control the amount of air i use. Yet it's not that big so easy to hide or place so not in the way
