REVIEW 2021 - DANNER MANUFACTURING, Inc. Supreme Oxy-Flow Low Volume Aquarium Air Pumps, AP-4 Aquarium Air Pump, 3.5-watt, 06404

Danner 6404 First Impressions

Great air pump.

We can hear the tank bubbles, but nothing noisy from the pumps at all. Not to mention tank depth, etc becomes a factor. And one to the additional accessories for extra oxygen output only. Buzzing, humming, vibrating- they were driving me nuts! I added a check valve to my airline tubing and works as expected. The pump works very well in my 75G tank. My 20H tank is in my office, 3 feet away from my desk.

Danner 6404 Final Thoughts

I hope this helps anyone.

I use this on a 5-way valve for a 75 gallon tank. Buzzing, humming, vibrating- they were driving me nuts! It has one air outlet so i used a spliter& ran a tube to each end of bubbler. I use them in my Tilapia tanks and Koi pond. I put a wire tie Tightly over the tube and barbs and it's perfect. Make sure the hose is connected well. This happened to me with this unit.
