USB Micro Brushless Ultra-Quiet Mini Submersible Micro Water Cooling Pump for Fountain Aquarium Circulating DC4V-6V 0.6-1.8W 150L/H

I bought this pump for a small diy canister filter I made for my nano 3 gallon cube aquarium and it works great and silently. It's been running 24/7 for months now. I really like it and it's very affordable.

I wanted to have a wave maker for my 10-gal fish tank. Most of them were too big and bulky. This one was tiny and has right amount of water flow for my tank. Plus, my cabinet has power outlet with USB outlet, so that worked good for me too. I had to put my hand-made sponge filter for the intake opening to avoid my fish to get sucked in. The suction cups are small, but pretty good quality. It makes bit vibration and sounds, but not disturbing at all. Air pumps make louder sounds. If you need a miniature wave maker for your tank, this could be worth a try.

I bought this hoping that it'll last however that doesn't seem to be the case cause after 24 hours the pump started making an awful noise, then 48 hours it hardly pumps and is loud af

I ran this little pump nearly non-stop for about 6 months. It did what I needed it for. I will say that the flow varies a lot for some reason. When first plugged it out was pushing tons of water then after about 30 sec lost what seemed like about half the flow. No idea why. Every time I unplugged it and plugged it back in it would do the same thing. It didn't matter for my application and the pump is still working (though I no longer need it so it's going in the junk drawer lol)

I’m very happy with this vacuum cleaner ., for the price it’s a very good item. The suction power is very strong. I will get another one for sure. A+++

Got it for a terrarium for my iguana. She loved to bathe in it but it completely stopped working after like 5 days

I LOVE this product. I now have 3 of them, which I use in nano aquariums/vivariums. They do not come ready to be fit with standard aquarium airline tubing, though, so I literally had to melt (by holding it over a candle flame) the plastic on one end. Then I forced in some stainless steel aquascaping forceps and pulled them apart, stretching the tube opening until it was big enough to fit over the pump outlet. Aside from that, though, it is practically silent and very powerful for its size. Would highly recommend -- 100% worth the price!

This pump was PERFECT for my homemade ceramic fountain! It is TINY but makes the perfect little stream. Because it is an inline pump it didn't need to be fully submerged to work. Very happy! Will be buying more. For reference, the fountain I made is about 2.5 feet tall.
