APS50 Silent Aquarium Air Pump for Fish Tanks,Black,10 - 60 Litre

I own a 190 litre corner tropical fish tank (see image attached!) as well as a smaller cold water fish tank and this pump is absolutely perfect. Having owned a number of cheap air pumps in the past (many of them loud and weak), this one has completely impressed me with its overall design, quality and specification and is the best pump I have owned. Let me talk you through some of the frequently asked questions you are probably asking yourself now: Specification: * Mains Powered (standard UK 3 pin plug) * 2 Watts * 50 L/H * 230v/50Hz Is this air pump powerful? I have found this air pump to be powerful but this is a difficult question to answer. Different people have different sized fish tanks along with different requirements and different expectations. In my experience of owning cold water fish tanks, tropical fish tanks and Axolotl tanks, this is one of the most powerful pumps for its size and I can use this no problem with a medium sized bubble stone. Do bear in mind this is the smallest air pump from the Tetra series and if you do require a more powerful pump for larger fish tanks then it may be a good idea to check out some of the larger models. Is the air pump quiet? When I first plugged this air pump into my electric socket I was horrified by the loud noise the pump was creating. The noise wasn't actually coming from the pump itself but from the actual output inside the fish tank whereby I was using a medium sized bubble stone. The pump was simply chucking air out at maximum power which the bubble stone was unable to cope with. I then found a little valve inside the box which allows me to control the pressure of the air output, after using this I turned down the pressure considerably and the air pump became much quieter, in fact I have turned it so far down (for use in my small cold water tank), so that there is a little trickle of air and it is now virtually silent. The key is to ensure you have the correct sized bubble stone to cope with the amount of air pressure you require, a bubble stone too small for the required pressure will create a loud noise due to the air coming out too fast. Alternatively you can simply turn down the pressure to reduce the overall noise providing you still supply sufficient oxygen for your own fish tank requirements. Please note, there is no bubble stone supplied in the box and this must be purchased separately. How long is the power cable? After measuring with a measuring tape I can confirm this is approximately 1.9m long (or 1900mm). Does the box come with everything required? No the pack doesn't come with everything required. An air tube is required to transport the air from the pump to the fish tank, this can usually be purchased from any pet shop for a matter of pence. The air tube is also required to operate the air pressure valve, which is a little valve supplied in the box which can be used to control air output (see images attached), which you can connect to the pump using a small amount of air tube. Also an air stone which is not supplied isn't necessarily required but it is strongly advised to use one. Simply placing an air tube into a fish tank without a bubble stone will just result in it floating around at the surface of the water unless it is tied down inside the tank. A non return valve is also strongly recommended to prevent water from being drawn back to the pump. Can the air output be controlled? Yes, as mentioned above, the box comes with a little air control valve which you can connect to the pump using a little amount of air tube. The valve can then be turned to alter the amount of air flow required, from a little trickle of air to maximum power. The air flow valve is not built in to the actual pump but can be used externally from the pump itself (see attached images). Can this pump be used with a fish bowl or small tank? Yes this is the ideal pump for fish bowls and small tanks as long as you have used the supplied air output valve. The air output valve can adjust the power of the air output and by turning it right down and using it with an air stone makes it perfect for fish bowls and small tanks. Without using the supplied air valve the pump would be far too powerful. What types of tanks can this air pump be used with? This air pump can be used with cold water fish tanks, tropical fish tanks and marine fish tanks. Can this be used with a Biorb? Yes this pump is perfect to compliment your biorb tank. This review has been based on my experience of using this air pump for a number of months, I hope it helps!

I bought two of these pumps because I run several aquariums and had been relying on USB air pumps, which worked quietly but failed far too often. I used to keep fish many years ago, and back then air pumps were incredibly loud, so I wanted something reliable and quiet this time around. Although this pump is rated for 10–60 litre tanks, I’m using two air stones in a 74-litre tank and it handles them with no problem at all. It’s also impressively quiet—almost silent—so it’s perfect for my setup. Just note that it needs to sit flat on its side to stay quiet; when I tried hanging it, it produced more noise. Overall, I’m very happy with this pump and will definitely be buying more, especially at this price.

This was purchased for a 50l fish tank to supplement a bit more oxygen to our fish. As the pump didn't come with any tubing, we purchased these separately along with a bubbler stone. The pump connected properly and we've not experienced any issues with it. As we have the pump on a self above the tank, it is a little noisy but I'm more or less used to it by now. You can adjust the strength of the pump and this obviously affects the noise it produces, but on a low setting it produces enough bubbles for us and it's not noisy enough to be distracting or unpleasant. On max power it looks like it would be good for a bigger tank too.

If you struggle with the noise an air pump makes then rest assured this tetra air pump really is silent. I have always believed that no air pump can be silent but when this one was plugged in there was not a sound, the air is a nice flow which is plenty for my small aquarium, it's easy to use, it's relatively small size, and the cable length is fair. All in all I would recommend this air pump especially if you are looking for a silent air pump.

So, my problem was really the noise... I'd purchased a BiOrb 15L fishbowl and it came with its own airpump and light (both powered by same mains transformer) but to my surprise the airpump shipped with the BiOrb was ridiculously loud. We keep the BiOrb on top of the chest of drawers in the bedroom, so you can imagine the noise factor was something extremely disturbing and needed be fixed asap! The only reason I've bought the Tetra Tec APS airpump is because it said on it "silent" I really needed to sort out the problem that I was having, which was as multiple times repeated in this post --- the noise. When I've unboxed the new received Tetra Tec my first thought is to plug it into the mains to see if it is quiet. It wasn't, I was so disappointed... but then I've placed my finger over the air nozzle and immediately the sound and vibration reduced to almost nothing. Ahuh...?!? Lesson learned: try the pump the correct way before jumping to conclusions. Connected to the airtube, with the flux reduction valve also mounted somewhere half way in the length of the air tube, this airpump works beautifully with the BiOrb.... And you know those nice advertisement pictures you've seen before buying a BiOrb that show the few bubbles here and there releasing into the fishbowl water, so minimalist, so IKEA-style? Well, you can forget about that if you use the airpump your BiOrb comes with. That airpump has no air flux reduction option, so you'll blow bubbles into your aquarium as if it would be an underwater vucano! With the Tetra Tec everything's as it should be: you can adjust the air flux as per need, there is no vibration noise when the airpump is placed on a firm, horizontal surface (not even if this surface is wood, ... and we all know musical instruments are built generally from wood, right?... and that's because this material has a fantastic resonance ability) and the best of all for me, it brings a solution to one and only problem I was so eager to fix: the noise. Ahhh..., so quiet... can you hear that?!? - listen... just the sound of the bubbles releasing into the water..., nothing more. Fantastic!

Out of the box it's practically silent. The only real sound you can hear the sounds of the bubbles it creates in the fish tank. My old pump was loud, but had started to get really loud and rightly the last few weeks even though I put cable ties around it and put it in a box. This one honestly barely makes a vibration. I will update if it starts to make noise but I'm so happy with it so far. My fish tank is in my bedroom (stupid move) but I slept like a baby last night with the reduced noise. The rubber feet seem better than the version I have before and really dampen any sound.

Broke after 3 months do not buy.

Good product

Silencieuse , pas très grande cet pompe a air est idéal . Je précise que cet achat est uniquement pour la pompe , le diffuseur pour l'air ainsi que le tuyau ne sont pas inclus pour ce produit .

No sé si me ha tocado a mí sólo, pero tiene el enchufe en formato inglés. No lo informa en la descripción. Me parece una broma de mal gusto. Muy mal Amazon, muy mal.

Very calm and silent pump. I was struggling with many other pumps till i found this one. Good for medium to small sized aquariums. Better use it with one tube for better results. For big aquariums better buy as well one way valve. Very good and silent product.

A close to silent pump, not completely, but better than all the ones I had. The only problem is that it came with a UK plug while ordered on Amazon.nl. On Amazon.co.uk I saw many people complaining they received the pump with a EU plug. I think someone made a mistake. :P Still 5 stars as the pump is great!

Les conseils données sur les correspondances volume aquarium / débit des pompes sont surévalués, j'ai pris cette petite pompe pour un 180l et trouvant que le débit était encore trop fort, l'ai partagée avec deux autres bacs de 30l. J'ai une également une APS 150 qui alimente un 250, un 60l et un 38l. Concernant le bruit, et contrairement à ce que j'ai pu lire ci et là ... elle est TRES silencieuse, bien souvent ce n'est pas la pompe qui fait du bruit mais la transmission des vibrations de celle ci aux objets avoisinants.
