HITOP Upgraded 2W Adjustable Single Outlet Aquarium Air Pump, 2.8L/M Mini Quiet Fish Tank Aerator with Accessories, Oxygen Pump for Small Tank up to 40Gallon

This is one of the best air pumps that I’ve ever used. It has adjustable airflow dial, and a perfect price.

I'll give this guy credit: this is the quietest air pump I have ever used. Literally cannot hear it when in use, and a welcome change from the Tetra mainstays I've used for years (and anything BUT silent). The most recent Tetra was on its way out, and thank the heavens for some finally peace.Still and let's be clear: this is a $10 air pump and is built like one. Plastic shell and knob are a bit flimsy, but...they do work. And this surprisingly includes a check valve, round air stone, decent flex tubing, and air control flow valve, again, all for under $10.This isn't the most powerful unit - I certainly wouldn't use for anything but an airstone - but it does the trick at near highest setting.Hard to say no at this price, just don't expect miracles. Does what it claims and well, and let's hope it keeps up.

Strong air flow best for price

Super easy directions for install, works great and has adjustable airflow. I don’t know how these work for fish but this is adding a substantial amount of oxygen to my propagation tank! Cannot wait to see how it changes the overall health of my plants roots!

This is one of my favorite air pumps available on Amazon. They're actually quiet, powerful, and usually last for a long time. I really like the adjustable flow feature (lower flow, less noise) and on the lowest setting it is almost silent. The supplied air stone and tubing works in an emergency but I usually upgrade those items as soon as possible.

The air pump itself is fine and does what it is supposed to.Unfortunately I ordered the 2.8L p/m version, which appears to be the pump I received, but it came with the 1.5L accessory kit. This means, among other things missing, it only included 1 suction cup.To make matters worse, the one that arrived does not have a suitable hook to hang the pump. It appears that the suction cup is actually for the tubing, even though the listing talks about hanging the pump on the back of the tank, which I was looking to do.There are also basically no instructions aside from some fairly vague ones about how to use the "regulating valve".This pump is close but they really didnt follow through on the promises of the listing.ETA: originally was a 2 star review because the listing was incorrect and showed more accessories. Seller reached out and explained the error and corrected it. This pump still does not include and mounting hardware but it would probably be 5 stars if it did.I did not accept any additional accessories nor discounts/compensation in exchange for updating this review. It feels more appropriate, especially for the listing as it's currently written.Seller...start including a suction cup with a hook 😉

Works really well! It provides a strong flow of air, but is very adjustable if you need a lower flow. It is silent & the feet do a very good job of dampening any additional vibration noises. It comes with all the necessary accessories to set up an air stone, but I am using it with a sponge filter and it is working very well. I would definitely recommend this product if you are looking for a simple, single outlet air pump.

I got this as a replacement for an old air pump that's been buzzing, and I'm so glad I did! This is nice and quiet and has a great air output. A feature I never knew I needed is the knob to adjust the flow level, and now that I've used this one I want to replace all my air pumps with adjustable ones!
