🐠 Efficient Tetra Whisper Air Pump for Aquariums (Non-UL) - Simplify Your Aquatic Aeration! Review

Broken in less than a year and certainly outside the Revain return period! Only one of the two outputs is sufficient to operate the sponge filter. The other is so weak that it hardly bubbles. I contacted the manufacturer and received the worst customer service I have ever experienced from Scott Bonomo. He didn't even read my original email and insisted that I buy a repair kit when I checked everything (opened the pump, took out each diaphragm and inspected it thoroughly and also replaced the…

Don't buy the Whisper 10! The 40 works great and costs a little more than the 20, which also works - you can control the airflow with the little valve that comes with the pump. I have five tanks that I have been using for over 8 years and they all use whisper pumps. When using air filters, I use slightly more pump than specified for the appropriate tank size. I bought two 10s, two 20s and five 40s pumps. I have 5, 10, 20 and 30 gallon tanks. Now I use 20 for 10 and 40 for 20 and 30 gallons. The

This pump is very quiet and works great. This product comes with: 1) the pump itself 2) a T-valve used to adjust the airflow. ) a bubbler or bubbler decoration with an attached bubbler. All of the above items you need to purchase are usually inexpensive and easy to find at your local pet store or here on Revain. Reassembly: Attach a standard air hose to the pump outlet. Give it a few inches and then cut it off. Insert T-valve. Connect the tubing to the other end of the T-valve. Give it a few…

As a mechanical engineer working with liquid pumps, I can easily see the strengths and weaknesses of materials or designs. Material and fit are mostly good. My device started jumping and falling 2.5 months after purchase. It's too late for Revain support and taking too long to get Tetra back under warranty. Looking into this, I found that the arms were not symmetrical, which in turn led to some variance in the output and work. Not a big issue, I found the reed valves were sturdy, felt like…

Got a Whisper 10 to replace the weak filter that came with the small air filter used with the 2.5 gallon betta tank. I've had it for a little over a year. It definitely started out quietly. However, I have experienced what others report as an increase in volume over time. I saw someone notice that one of the stationary magnets inside was loose and vibrating against something. That wasn't the case with mine. I found that the rattle is coming from the housing that the pump sits in. The two sides…

I have been running aquariums for 45 years and these air pumps, while not entirely 'quiet', are as quiet as can be - unless of course you don't places them Don't pump into the next room and run a hose through the wall into the tank. Don't laugh, this is fairly common among serious aquarists who love bubbles and can't stand the noise. You see, over the years I've had just about every popular and affordable air pump, AND NONE OF THEM ARE QUIET. Many are downright offensive. It's quietest to do…
