Review: Simple, Effective, Customizable...Deal - 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 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: Amazing Mini Filter! - 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.

## Questions & Answers

**Q: Can you make the water level less intense? 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!!)
