TetraWhisper Easy to Use Air Pump for Aquariums (Non-UL)

Got the 100. A tad bit noisy, but it gets the job done.

Rating: 4.5 starsWould I recommend? Yes!My current tank setup is a 40-gallon breeder with one axolotl. We had still been using a cheap, unbranded air pump designed for our old 10-gallon starter tank for the past year and a half or so; it still worked and produced sufficient air to power two bubble accessories, but was loud as sin. Especially when the tank chiller was going at the same time, the noise level was really annoying.Since we're home all the time now during quarantine, it got really irritating listening to that air pump, so I did a lot of research that led me to the Eheim brand of pumps. They supposedly had the best power and noise level. I ordered the Eheim 200 (which is supposedly overpowered for my 40-gallon tank, as it's rated for 60 gallons) and returned it the same day I received it. Even with BOTH of its outputs combined with a T-connector and cranked up to maximum output, it was not strong enough to produce ANY visible bubbles, even when connected to only one bubble accessory. It was pathetic: yes it's quiet, but that's because it doesn't do anything! I don't think we just got a dud, either, as we could feel the air output on our hands, it was just very weak. We were very disappointed. It was not at ALL worth the price, and functioned worse than our cheapo beginner air pump.Next up, I finally decided to try the Tetra whisper. We read from a reviewer who tested the output and dB of many pumps that this one was NOT the quietest, but was efficient, inexpensive, and quiet enough for the price. I was also still wary of many negative reviews. After my previous disappointment, I really considered getting a Tetra pump intended for deep water application (overkill, but we wanted to make sure this one actually worked!) but finally decided to compromise on a Tetra Whisper 100-gallon pump. Unlike the Eheim, it doesn't offer built-in output controls, but it does have 2 outputs. I really only need one output, and the power is still overkill, but thankfully... this one WORKS!The device is easy to set up, and functions well even when both outputs are connected via a T-connector (I also use a one-way valve at that point just to prevent backflow). We have the pump itself plugged in inside a cabinet under the tank, and we run a line up into the aquarium via a hole in the lid. I then split off the line with an air manifold inside the tank itself and have it hooked up to two bubble toy accessories. I am delighted to report this is capable of powering both, without producing an excess air volume. Our axie likes to hang out near the bubblers.Best of all, this pump really is quiet. It does produce an audible low hum when you're nearby, but does not rattle and cause other things in our cabinet to vibrate loudly like our old pump did. The volume is negligible when not standing next to the cabinet with the doors open. It is actually a huge relief.I would recommend this product over the Eheim pumps especially, and would advise others to go for a significantly higher volume rating than their tank volume if they intend to power anything more than a bubble wand. I also recommend purchasing a T-connector with one-way valve if you need to power a single accessory that needs more air power, such as a filter.

Great product. Has worked very well.

This air pump is significantly more powerful than the smaller version, making it perfect for larger tanks. However, it is a bit noisier compared to its smaller counterpart, which might be something to consider if you prefer a quieter environment. That said, its performance more than makes up for it, and overall, this is a great product for anyone who needs an efficient and reliable air pump. Highly recommended!

Great item works very good.

Works great & super quiet! Much cheaper than regular stores too.

The Tetra Whisper Air Pump for 60-100 gallons is an excellent choice! It delivers strong, consistent airflow while staying surprisingly quiet for its power. I use it for my large aquarium, and it easily runs multiple air stones without any issues. The build quality feels solid, setup was simple, and it’s very affordable compared to other pumps of this size. If you need a reliable, quiet, and budget-friendly air pump for a larger tank, this is a fantastic option.

I've bought at least 6 of this type of air pump and every time, I gave a raving review. Until now. This is the first time buying the "100 gallon" item and I'm a little disappointed. It pumps air like it should but this larger unit is VERY LOUD. I've tried everything, from adjusting the air flow to wrapping the unit on a towel. But it's still loud. I finally just had to unplug it.Since I've so much luck with this pump before, I believe I'm going to try buying a new unit and see if I have better luck. Maybe the one I got is just a dud.
