DaToo Aquarium Hang On Filter Small Fish Tank Hanging Filter Power Waterfall Filtration System

Truth be told I was concerned about getting this HOB filter for my 2.5 gallon shrimp tank due to some critical points other reviewers made. So you know where I'm coming from, I do have a larger 30 Gal general tank and I've typically had bad experiences with HOB tanks that have the pump outside the of the tank. I tend to do better with either "self-priming" HOBs or Internal filters. However, for a 2.5 Gallon tank, internals take up too much space for the aquascaping I wanted to do and the only "self-prime" HOB I could think of that would fit was no longer produced (Marina S5). So I had no choice but to go with this HOB that had the motor on the outside. And it's actually really good.So my thoughts as to why I really like this one:1. This filter is small and slim, but has ENOUGH space for me to customize the filter media (see pictures).2. Super quiet...in fact my air pump is louder than it. The main feature that helps is that there is a rotating piece you can turn to put some space between the tank and the motor. That's the key there. I had rattles when it was up against the aquarium, but now that I turned that disk and created space, you don't hear anything but the trickle of water (when I turn off my air pump).3. It comes with a suitably sized pre-filter that covers the intake pipe. My shrimp have safely climbed on to eat some of the food on it and combed off. It is coarse, but for a pre-filter I prefer that as it sufficiently catches large debris without greatly diminishing the water suction. I mean, I want most of the filtering to be done in the chamber anyways.4. Easy to take apart and clean out sludge5. The suction isn't too strong for my tank community. No one is fighting the current like they initially were when I tried an internal filter system.6. It's size is easy to manage and work with while still being big enough to do a proper job.Things I learned to be aware of:1. One other reviewer mentioned that this pump had sucked out water out of the tank and spilled it outside the tank. THIS CAN BE TRUE. It actually happened to me also, BUT I learned that there is an easy fix and it hasn't repeated that problem ever since. Simply put, I initially over stocked the chamber with media so it ended up displacing the water to much that it spilled out of the filter. I stripped it down (see the picture) and it works like a charm. No spillage...not even a little water dripping out of the top. And the biggest culprit was that I had a sponge that was way too dense in there.2. When using an HOB this small (especially for a planted aquarium that uses soil), it will be necessary to clean the filter once a week. This also helps to prevent overflow. It's the nature of the beast.3. The noise issue can be real as another reviewer noted...but just as I stated, the rotator disk they have at the bottom of the motor makes the rattles disappear. Again, the key is putting a gap between the tank and the motor component of the HOB.So all in all, I am pleased with this purchase and will be going for this filter again if I ever require one for another nano tank.

First, the price was very good (among the lowest cost aquarium water filters). Works beautiful right out the box. Noise is noticeable but not loud. It pumped the perfect amount of water that I need for a 10 gallons fish tank. I had two previous filters before but they were too strong for my fishes. I saw two of my neon tetras died and the big male betta was thrown around like a ragged doll before I order this new one. Just remember to fill enough water to help start the filter, otherwise it WILL NOT work.

For what it is, it does it's job at a very good price. It's not quiet though. You will hear a hum.

Worked fine for two months, then the gasket failed between the filter body and the electric motor and the filter dripped out all the water in the filter system. Fire hazard, electrical hazard, and is not fixable. Don't waste your money on this small filter with wimpy gaskets which wear out.

This filter is great for any small or nano aquarium. Probably not great for anything over 5 gallons but could probably handle up to 10 gallons. For the size, the pump seems pretty strong. It's a small filter.As for filtration: It comes with a proprietary filter insert that has a mechanical filtration membrane on one side and a chamber containing a tiny amount of activated carbon. Typical for a small on board or in tank filter of this size. Needless to say the filter insert is junk. You should discard it and replace it with plastic pot scrubber material from the dollar store, or get bulk sponge filter material from the local fish supply. What you want in filter media is lots of surface area and enough space to move water through. The included round sponge that goes over the intake is adequate, and safe for shrimplets.

i never review products, usually i really don't care to share my opinion. but this is the single most quietest filter of my life. i kept thinking it broke and shut off. it makes ZERO noise. not even water sounds.nothing comes from this thing it's AMAZING

I recently set up my first shrimp tank. It's a small cylindrical bowl/vase that can hold between 1-1.5 gallons of water. I originally planned on going filterless but after seeing that a really small filter like this existed, I thought I'd might as well try it.I was a bit hesitant after seeing some reviews say that it buzzed/hummed loudly. The tank is right next to my bed so I definitely would not tolerate any kind of noticeable noise coming from it if I were to use it. Thankfully, like other reviewers noted, as long as you rotate the circular piece at the bottom of the filter to keep it in the right position, the filter is actually as close to silent as you could hope. I literally have to put my ear right next to it to hear anything from it (and I have pretty good hearing).When I first set up the tank, with just the plants and water, biofilm developed on top of the water. It took a few hours of running the filter to clear the biofilm from the surface of the water and now it's crystal clear! After just a couple of days, I can see gunk accumulating on the pre-filter so it's definitely doing its job!Since I have such a small tank, I was also concerned about the intake pipe being too long. Thankfully, you don't have to use the connecting pipe if you don't need it so it's also the perfect length for an aquarium that's less than 5 inches deep. You can also easily adjust the water flow and I have it turned all the way down. It creates a VERY gentle flow that doesn't disturb the floating plants I also have in the tank.I've only been using it for a couple days at this point so I can't speak to the longevity of the product but so far I'm very impressed with the filter, especially considering it only cost $8. I also bought a few extra pre-filters and plan to add some ceramic rings to the filter as well.

I purchased one unit for my 3 gal nano tank with guppies and live plants. Very simple set up and installation, quiet and seemingly effective with great flow, even came with a rubber piece to secure to the tank rim to add extra noise barrier. I did consider buying a more dense sponge to help keep floating plants from getting sucked into this sponge as I noticed this being an issue in all of my tanks using this filter but overall, quite and attractive for my rimless nano tank and easy to clean. Or at least first impression…After a month I decided to buy 3 more units for my other nano tanks since I was overall happy with the purchase. All 3 units arrived and all same contents in the box MINUS the rubber tubing for the tank rim to create the noise barrier. This was frustrating but given that all 3 were missing it, I assume this piece was discontinued as part of the setup?Quickly installed all 3 units to my 3 and 5 gallon tanks which I have scatted throughout my house. All is going well but on these units, about 3-6 weeks in, they are no longer whisper quiet. They make very LOUD humming noises and semi rattle against the tank. I cleaned them thoroughly to ensure there’s no build up of any kind causing poor circulation/flow but even putting it right back on, it’s just about the same.I have one in my office on my desk and the noise is so loud it’s distracting during calls and I find myself constantly fidgeting with it, trying different placements and lodging things between the filter and tank to add a barrier but it’s short lived fixes. The one in my bedroom is probably the worst as it now keeps me from sleeping as the noise will often gradually increase over the course of the night.The first tank set up doesn’t seem to have this issue, at least not to this extent, makes some slight noise but It’s nothing compared to the rest of what I am experiencing. It seems the missing rubber tubes really make a huge impact and are necessary for a pleasant experience with these filters. Not sure why that piece has been discontinued but it should definitely be a necessary component included for best possible experience and user sanity. Purchase with caution as I am now in the market for new truly quiet nano filters.

No hace nada de ruido y funciona muy bien. Le puse una plantita.

This is a tiny filter as u can see fits in my palms, great for nano tanks, u can adjust the water flow too. I have it for my beta tank (about 1.2 gallons) but I will put him in a 3 gallon tank along with this filter. it is quite noisy, but I put a piece of paper towel between the filter and the glass and noise is 99% gone. Great quality so far for a tiny filter!

Muy durable, resistente, consume muy poca energía, y además que en mi sector se va mucho la energía eléctrica y ha aguantado los bajones de luz

I use this filter for my small shrimp tank and it works fine. The build quality is good and the noise level is acceptable. I cleaned the filter with tap water so I don’t need to replace the filter very often. If you are looking for a low budget filter, you should consider this one.

This tiny filter works great with my son's 1.5 gallon tank. It has more suction power than the old tetra one that came with the tank. The current on the lowest setting is perfect for his betta. It is a little noisier than the last filter though. So far, I'm satisfied, I just need to look for filters that will fit the chamber. The filter cartridge has an odd shape.
