HITOP Quiet, Adjustable Aquarium Air Pump - Upgrade for Maximum Oxygen Output

K. Pickett: Replacing a whisper brand air pump in 30 gallon turtle tank. Much more quiet than the Whisper model, which was constantly having to be jiggled to reduce vibration noise

George M Flanigan: This pump is quiet. I 'm using it on an LED air stone and it works great because I can adjust the amount of air coming out.

Noah Kokkinias: I love these air pumps, very durable and have lasted me two years. Being able to adjust the air flow is a big bonus. Make some noise but it’s not obnoxiously loud. Great buy!

The Reverend A.J. Miller: bought this for my 2 countertop hydroponics systems, as my research led me to think that aerating the water would help plant growth. Came with everything i needed, including 2 airstones, 2 inline pressure regulators and a T splitter (along with other stuff i may use on other projects).

i guess all those websites and forums were right, because after 2 months (and 4 root trimmings), i had to take several plants out of the hydroponics and put them in pots because they had gotten so large. some of that may have to do with better nutrients and pH level maintenance, but it cost less than 11 dollars.

I ended up purchasing black air tubing (which came with cylindrical airstones that i now use instead of the globe-shaped ones that came with this pump), but all the connections work the same.

the adjustable output knob is a nice touch, but it can be a bit finicky to get your level just right, especially with changing conditions (i.e., root growth). I have the pump set at a level where i cannot hear it from 8 feet away. The problem is not actually with the pump itself, but rather with the noise the airstones make.

the only thing i didn't like was that the check...

Lisa Woods: I threw them out before I thought to take a picture but the airline tubing that comes with the product is too wide that it repeatedly falls off the connectors essentially unplugging your air stones over and over again. I had to reconnect it constantly, like at least twice a week. It also got discolored and started to expand within a month of purchase. Air stones and pump work great, very powerful even when set to low pressure. The pump is pretty loud, I had to put a cloth underneath to help with the sound which is pretty much standard. All in all a great product and good value for your money, but don't waste your time with this tubing. Even if yours fits great it will still discolor abnormally fast and expand until it doesn't fit anymore. I got tubing from Walmart and it looks and works great I haven't had any problems and it was only $5.

Amazon Customer: I am not a great "horticulturist," so I allow an automatic waterer feed my plants for me. However, I don't like the idea of having a five-gallon container of stagnant water and fertilizer mixture sitting around so I got this pump to aerate the tank that holds the liquid plant food. I liked the idea that it came complete with air stones, tees, hoses and other accessories. I also liked the feature of being able to adjust the air flow. When the pump arrived, I promptly pulled it out of the box and plugged it in. It began humming and I could feel the air emitting with my fingers. As I turned up the adjustment, the air got stronger- so far so good. I then looked at the accessories. The air stones looked fine, although I already had a long, thin stone that I was planning to use for this particular application. I knew I would not need any of the other accessories except the hose and one of the tees as I was going to join both outlets together to run one stone. I immediately noticed that the hose was very soft and "mushy." I tried to push the hose onto the tee, and finally got it seated with some effort. When I tried to get it seated on the pump outlet barbs, that really took some doing...

Michael Boerefyn: I have a large Fluval 55 gallon in my bedroom so having a never ending hum was the last thing I wanted. I have a few other air pumps like the Tetea Whisper which is way more noticeable than the ITop.

So quiet I kept check the tank to see if there were bubbles.

I also like the adjustment dial. At max flow you can hear it, but under 3/4 you won’t notice it.

Anya Darling: It’s a little noisy on the highest setting but my turtle loves the bubbles so it’s worth it. Took me 2 minutes to set up, cheap and doesn’t take up much space!

Ma: An updated review! .. I have had this item a couple months. I said b4 that for the price, it’s a little noisy but okay…well now I’m very disappointed to say this pump is now,barely working. It’s been maintained and treated well, but I already have to replace it very soon or the fish will die. I’m upset about this for many reasons, and by the time I do get to town to get another pump it may be too late for my fish.
