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 sludge 5. 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. Review: Small Water Filter Works Great!!! - 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. ## Features - DaToo Aquarium Hang-On Filter: Owning a successful aquarium is the dream of every aquarium hobbyist.

My tank is small** A: You can adjust the water flow. It is a plastic turn non that adjusts how much water comes thru. **Q: I asked when the replacement filters would be available and was told 2/5/23. I tried to order but it says it ships in 3 months?!!!** A: Thank you for loving the DaToo product. Don't worry, please be patient for a few more days, the replacement filters will soon be returned to stock. It won't take this long, Please just be patient for a few more days as the Amazon warehouse staff have not put the new stock on the shelves for sale yet. Once the new stock is placed on the shelves, you will receive it soon. **Q: 7.3" is the intake all the way down? How many inches if the intake all the way up? Thank you** A: Not sure if this answers the question but the intake or tube hangs a little more then halfway inside the tank. Or about 5 inches from bottom. My tank is 3.3 gallons. **Q: I have already purchased the filter and only now did i paid attention that it is for 60hz 110v. just to make sure: no way it will work at 50hz 220v?** A: You need to buy an additional transformer to convert 110V to 220V. (Note: Before use, please turn the knob at the bottom of the filter to adjust the distance between the filter and your fish tank, otherwise it will cause noise and shaking. Very important!!) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Simple, Effective, Customizable...Deal *by H***S on November 5, 2022* 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.
