    • For the price, this is an excellent quiet little filter
Size: Magi 380: 10 - 20 gal
For me, noise-level was the most important factor. I was nervous when I first bought this because I've purchased filters that promise to be quiet and they aren't. The NICREW filter is great. Works as promised. It's not super-dooper-uber quiet - but certainly a heck of a lot better than those Tetra 'Whisper' filters. Absolutely the quietest in this price-range. While I recommend this product and gave it 5-stars just know a few things: 1) While the replacement filters aren't expensive - you're going to have to get them from the manufacture / Amazon. (You can make your own ... but I'm gonna guess most people buying this are new to the hobby.) 2) If you place the filter to deep in the tank, the air-flow will suffer since it will take more work for the engine to draw in the air. For the record: I have a 20 gallon tank. ... show more

    • Small but powerful

I ditched my sponge filter because it couldn’t catch larger particles in the water. This little filter is 2 stage, with a larger sponge and then a charcoal pack. It churns out lots of water for such a small unit. The other reason I switched was that the air pump was a bit loud and I could never get used to the constant drone, especially at night. This filter also does a great job of aerating the water, so an air stone would no longer be needed. I get more volume, more circulation, great aeration and better filtration. Easy disassembly for cleaning. Takes a minute to clean out. It comes with a rain option as well. The tank wasn't getting much circulation before, but now the water is flowing well. There are enough spots in the tank for the fish where they don't get pushed around by the water flow and can chill. I like this filter a lot and I would use in additional small tanks if I add more. ... show more

    • Working well in a 5 gallon betta tank

Fairly quiet, low price, and keeping the tank clean.

    • Cheap but very good
Size: Magi mini: 2 - 5 gal
I used this type of filters before in other countries and all of them worked perfectly. If you want to use it for bettas in a 2.5 gallon it’s too powerful. The quality is good. It’s not noisy at all. I’m satisfied with the product.

    • Frustrating
Size: Magi 380: 10 - 20 gal
Update: I gave up on this. It gets clogged up so easily, I was having to clean it every day or it would stop working right. I've got 8 tanks, I'm not inexperienced but I struggled to make this filter work correctly. I went back to a sponge filter and my tank is so clear now! I should have kept it running instead of this filter. ________ I've never had so much trouble with a filter before. I was using an internal sponge filter and switched to this filter because the tank is in my bedroom and the bubbling was annoying. The pieces aren't great. I wanted an elbow piece to attach to the spray bar so the spray bar was vertical with the filter but the pieces don't fit together to make this. *Edit: if you use enough elbow pieces you can do this but the spray bar is very long I keep having to clean this filter out, things keep getting stuck to the slits on the side where it pulls in water. You would think that's a good thing but it blocks the filter and then the air tube and regulator stops working and doesn't produce bubbles anymore. If you have the air tube and regulator on it helps to turn the tubing inlet so it is horizontal, it seems to keep the water from going into the tubing, th water stops air from coming out when this happens. It's also very loud. I don't know if it's the regulator that is bad or what but the bubbles are really fine and they crackle as they come out. You can close the regulator almost all the way and it is still loud, sometimes it sends the air out in short loud bursts. Ramshorn snails keep getting stuck in the part of the filter where different arts connect, they are getting their bodies stuck in crevices then they can't get back out and they die. I learned this the hard way when I went to pull one off the filter and I pulled it's insides out of its shell. As of right now I definitely wouldn't recommend this filter ... show more

    • If it's good enough for MD...
Size: Magi 380: 10 - 20 gal
...then it's good enough for me! After setting up an initial planted tank, the "internal" filter I originally purchased was not working for me. This filter is MUCH smaller than the one I replaced, however it is just as powerful and with a more customizable and direct stream of flow. Before this filter, I had almost zero surface agitation and flow throughout the tank and always had a bio film. Now, I have the spray bar pointed up at the water surface from below, and I have very nice surface agitation and a gentle circulation throughout. My fish are not struggling with the flow, and all of my plants have slight movement at each location within the tank. It's smaller size is a plus to me as it takes less physical and visual space. The caveat, is that there is less overall filtration capacity. That being said, it is customizable to place biomedia or filter media as you wish. I ditched the included carbon bag, and used the plastic compartment to place ceramic rings for bio as the last stage. I also cut the foam in half and placed a fine filter floss as the second stage, and the remaining half sponge for the first stage mechanical filtration. It is very quite during normal operation, if it is making any sounds it's either time for a clean or something is broken. Maintenance is simple; simply remove the filter during a water change and via the bottom compartment remove the sponges and was in the old tank water. As mentioned above, you may be doing this weekly due to the overall capacity of filtration media volume. ... show more

    • Perfect for a small tank

I searched and searched for a small filter and this one is perfect! I love that I have options on how to set it up. My guppies love the waterfall feature and often play in the bubbles.
