KEDSUM First Impressions

Lots of bubbles.

I have to put my head behind the tank to hear it! I have an undergravel filter and a few other accessories that push air too. It didn't blow air out that line, while it still had a little water in the unit! The added tubing and manifold make this an even better value. Apparently the dome shape plays a significant role in noise reduction. The first lasted about two years when one side decided to put out less air. I'm not going to knock the product for my own paranoia though.

KEDSUM Final Thoughts

It is good and quiet.

Considering the warranty and performance, I upgraded my rating by 2 stars. It pumps out enough air to keep millions of air bubbles going in this 200g+ Aquarium! Make sure the hose is connected well. Almost all people will be highly satisfied with this unit. Once, the water in this tank backflowed into the unit. It could easily run a small fish room. My 20H tank is in my office, 3 feet away from my desk.
