Mini Aquarium Pump Wave maker For Aquarium USB Power Connector 530GPH (2000L/H) Circulation Water Pump 5W DC 5V With Magnetic DC Powerhead For Tanks Up to 14 Inches And 5 10 20 Gallons Fish Tank

This is a great little pump I used this in my 8 gallon bio cube nano reef aquarium it works great if you have a spot in your aquarium that you don't have good flow this is a good pump for that. I am going to start a new 20 gallon hexagonal aquarium in a couple of months I will buy 2 of them for this aquarium. it is DC power and I can use it with my back up battery pack

Hmmm this worked perfectly until it didn’t. All was well, it’s small enough ✅ quiet ✅ multi-speed✅ and multi-functional….. the all of a sudden flashing lights and malfunction is a huge blower. I’m reaching out to Amazon and the manufacturer now.

I love this little thing. Used it for about 5 months in a 29 gallon tank to eliminate some dead spots in a reef tank, and now moved it to my 40 breeder to eliminate dead zones. It's powerful, I have it set at about 50% right now and it provides tons of wide strong flow to disrupt algae growth and stir up detritus. Never had problems with livestock getting inside it as the cage is very secure and it is low profile to the glass. Also it's very easy to take apart and clean, and it never stopped working the whole time I've had it (8 months) I have maybe cleaned it 3 times and it doesn't even care. Controls are also easy to use and figure out, and it has enough settings to justify the price.

1.5 year update: I think I just got used to the noise. I had been running the replacement pump for the past yearish. It began to display the same issues as the first pump. I just kept using it as it would fail predictably. Turning off and on every few seconds with a pulse of water. So it basically just turned into a wavemaker, worked for me. I finally upgraded to a proper sized tank and began using my nero 5 again. I attempted to use this small pump to cover up some dead spots but quickly realized it had been producing this irritating clicking noise. It never really bothered me when it was set up in my previous tank as it must have come on gradually. I checked the pump all over to see if anything was hitting the shroud, nope. It continued to give the errors previously stated as well. Anyway compared to a proper wavemaker they have a motor drone and with the vibrations from the pump it was a no go. As it goes they seem to last about 6-8 months before issues arise. Makes more sense to me to buy a different brand. My nero 5 at 240 dollars has lasted 5 years and is still pumping. So, cost/benefit it to see if a Nero 3 or similar high-end wavemaker would suit your wallet better. 8 month update: This device continued to operate normally until about the 7 month mark. I have regularly cleaned it by taking it apart and ensuring all components were free from buildup. However, it began to malfunction. It would attempt to spin up and push water but would quickly flash orange - indicating an error. The pump would then stop spinning for a moment and restart this process. It led to a small wave being pushed randomly every 3-6 seconds. It didn't matter what flow mode or power setting it was adjusted to. I reached out to the seller and they offered to replace the item. The new one appears to have a few updates. The controller has a different printout on it showing what the flow mode colors mean. There is also a textured backing added to the silicone on the powerhead itself - I suspect to help in holding the powerhead on the glass. Other than that. It looks pretty much like the same thing. For the cost of 40 bucks to get 7 months of operation? Not great. Not horrible. It's still the smallest powerhead I'm aware of with this kind of flow....so...can't complain too much! I'd still buy it again. Original: I took a chance on this listing. No reviews and an overseas shipper. I purchased the 570GPH 5W model for 39.99. They gave an estimated arrival date of may 10th to june 10th...but it arrived on the 5th of may, so that's nice. I have only had this for a day but wanted to provide some insight as the listing as pretty poor and lacks much information. The dimensions of 1.6 by 1.6 are accurate, this thing is definitely very small. It is powered by a USB A plug which I prefer as I can run it off a multi USB outlet and save plug space on my strips. It comes with a reasonably written manual, a bunch of stickers (that I don't understand the point of), a velcro strip for the controller, 3 covers for the pump, and a USB power source. The best I can tell it has 3 pump modes. It has constant, pulse, and a slow pulse. You can only adjust the pump's speed and not adjust the pulses' timing or anything like that. I ran it out of the water and it didn't like that, giving me an error state flashing light on the controller. This shows it has some feedback built in. It almost reminds me of the TMC nano flow 1000, but it hasn't been released in the US. The dimensions, power source, and look are the same, so it could be just a rebrand. So far it seems to perform reasonably well. I put it in a tank that's still getting off the ground so I don't have corals to check about its flow. However, It moves a reasonable amount of water in a 15 gallon tank. It's silent while running. The included covers do adjust the flow and allow the flow to spread out a bit. The magnet doesn't seem to have any issue holding the pump through 6mm glass. I have a nero 5 in my other identical tank which is just complete overkill. So I don't really have a good comparison. I would say in the IM 15 AIO tank I would want 2 of them. One towards the front and another on the opposite rear. I included a photo comparing it to the nero 5 in the tanks. The nero can fit at least 4 of them inside it. I'll update this over time.

This wavemaker pumps works well for gentle water movement. I use this in my 35g saltwater tank with corals. The other pumps I've tried were way too strong and were damaging my coral. The stickers and most of the manual are not in English, but the controls are intuitive. Also, the motor is quiet, but you can hear it some in a very quiet room.

Love the size of it, It worked great for about 3 weeks then it just stopped working now I have blinking lights. It's in a saltwater tank I figured it would work but maybe it's something with that goes and it might work. Kind of disappointing

The fact of the matter is, the device is tiny and has such a small profile that the 1000 lph flow rating is probably not accurate. If you need to add some flow to a pico or nano reef then this is a solid budget option. It basically has the same functions as most of the high end wavemakers on the market but at a fraction of the price, no complaints. That being said 2000 model is best for something like a 5-10 gallon tank. I would advise getting the 3000 for anything more than 10 gallons. This product is great for circulation and wave making in small volumes of water.

It works, very basic, does its job tho. Not much control over the flow rate has + & - but cant really notice a difference. It is quiet and compact thats nice. Personally think my jerepet one is better, better design and controller for similar price, gph, and size.

Absoluter Schrott…sehr laut im Wechsel bei Wave …und nach nicht mal 6 Stunden schon störungsanzeige Finger weg

good for 5 to 10 gallons only. Very very weak flow ; Too expensive for the technology and small product.

Perfecto para acuarios pequeños se ve muy bien y tiene suficiente potencia

What a compact and very well made wavemaker this is , tiny and perfect for saltwater nano tanks

I was really scared. I used to have another power head 5watt, and it was too strong. I now have this in the lowest setting on intermittent and it is causing turbulence in that corner but the rest of the aquarium is fine. I love the magnet, I love that it takes little space, and it is soft yet strong enough to circulate water on my wide-ish aquarium (60x30x30cm). My khuli loaches also love it!
