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

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.

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

My only regret is how many more I want now. It makes zero sound, minimal footprint, it's not overpowering. Absolutely perfect fit in a 10 gallon. My glass is pretty thick and it holds very well. Came with a ton of stickers that I don't understand and 3 diverter styles.While I was not worried about any livestock I am losing small bladder snails to it which obviously not a concern but I do think a small thin foam sleeve cover for it might not be the worst idea. I don't use any of the wave modes though they appear to work fine. I don't see a huge difference with speed adjustments either but again the freshwater makes it difficult to discern.4 month update: bought a second unit. Still great. My only complaint is the occasional snail shell gets stuck in it.

I just got this today. I have a 16 gal coralife and I only needed more water flow to get the gunk off the live rock and help circulate the waste off the sand. In a matter of a couple hours, this has helped a lot. In fact, I'll probably have to clean the sponge and filters tomorrow. It's very quiet and I wouldn't even know it's on if I couldn't see the flow of the remaining gunk. I have it on the lowest pulse setting right now and my fish are getting their exercise. Doesn't seem to bother my shrimp and the corals are open. I would say this is worth the price right now. I got insurance on it...just in case. I would definitely recommend at this point.

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.

Junk. This is the second of these units that I’ve received, the first broke after three months, less than a week out of the return window from the manufacturer, this one, the second I received, lasted approximately 2 weeks before stoping working. DO NOT ORDER. Pure trash.

The media could not be loaded. 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.

Perfect size for my Biocube 16 but stopped working in the auto mode after a week. Have to use the fast mode for it to work. And the fast mode is now only a medium speed. If power goes out I have to take front off, put it in the water and spin it with my finger to start it spinning again.
