  • Fits a small 1 gallon perfectly
Size: 1-5 Gallons
The media could not be loaded. I recently purchased the NICREW Slim Aquarium Filter for my 20-gallon freshwater tank, and I have been really impressed with its performance so far. The slim design of the filter is perfect for my small aquarium as it doesn't take up too much space, allowing me to maintain a clean and minimalistic look in my setup. The installation was very straightforward and the adjustable flow rate feature provided me with the flexibility to customize the water flow according to my aquarium's needs. One of the standout features of this filter is its quiet operation. I was pleasantly surprised by how silent it is, especially compared to some other filters I've used in the past. It's virtually unnoticeable, which is great for maintaining a peaceful environment for my aquatic pets and for my own enjoyment. In terms of performance, the NICREW Slim Aquarium Filter has been doing a great job of keeping the water clean. The filter media that came with it seems to be of good quality and effectively captures debris and particulate matter, leaving the water crystal clear. I've also noticed an improvement in water circulation and overall water quality since I started using this filter. The build quality is impressive, and the overall construction feels sturdy and durable. The adjustable intake tube and spray bar included in the package provided me with options to customize the filter to my specific tank setup, which I found to be very convenient. Overall, I'm very satisfied with this purchase. The NICREW Slim Aquarium Filter has exceeded my expectations, and I would highly recommend it to other aquarium enthusiasts, especially those with small to medium-sized tanks looking for an efficient, quiet, and space-saving filtration solution. ... show more

  • Performs marvelously! Exceeded expectations for my 3 gal. aquarium!
Size: 1-5 Gallons
My 3 gallon glass aquarium was purchased as a kit (Top Fin). The glass tank is rimmed to accommodate a cover, light, and in-tank filter, etc. The in tank filter was adequate, but took up tank space and my Nerite Snail kept crawling into the filter. I always preferred external filters. However, with a small dedicated filter spot, I thought I was stuck, until I found this NICREW slim. Fits perfectly in the dedicated cut-out. I especially like the adjustable flow control and that I can service it without disturbing the tank. Filter changes are easy, and my snail can’t crawl into it and get stuck. This NICREW filters very well and the filtered water is directed out across the top of water, rather than down. Granted, I can’t close the filter lid, but I always kept it open anyway for fresh air circulation. I’ve had no issues with noise like some complain, except the initial start up. I’m happy, the tank keeps clear, and the tank occupants are happy! WIN-WIN-WIN! ... show more

  • Really quiet filter for people AND fish
Size: 1-5 Gallons
Have a UNS 45s shallow planted tank with 6 or so Medaka in it. Been looking for a filter mostly just for water circulation and oxygenation. I got a tetra whisper 4 at the recommendation of reddit and to their credit it is very quiet, I can't hear it sitting six or so feet away. However the biggest reason I didn't use a filter for a long time was because I was concerned about noise pollution causing stress in fish. Its an understudied topic specifically in aquarium fish but we do know that noise pollution in natural bodies of water does negatively impact fish in a number of different ways. So while I was very happy with how quiet the tetra whisper 4 was for me, when I put my ear ear up to the glass of the tank I could hear just how much noise it makes for the fish. Granted, I don't know if the fish care at all, but I was still looking out for a better option that was also still silent for me. Enter this filter. Even quieter from my perception compared to the tetra whisper 4, and the hang on back design means that the motor is outside of the water, and doesn't contribute nearly as much to the noise level inside the tank versus the Tetra whisper 4's submerged design. When I press my ear against my tank all I hear is a soft low hum, which I hope the fish appreciate. Anecdotally from what I've seen so far the fish are much more willing to spend extended time right up against the filter playing in the current. So if you want a quiet filter for yourself and maybe are concerned about noise pollution for your fish, consider getting this filter. Its cheap, and has a nice reservoir that if you don't want to use their filters, can fill with an alternative media like ceramic bio rings. The filter also has an adjustable flow rate which the tetra whisper 4 does not, and the intake element on this filter comes with a sponge to prevent an unlucky fish who wanders too close getting a fin ripped off. Anyway the Tetra Whisper 4 is still a quiet and a decent filter but for the money I would say this Nicrew slim filter beats it in literally every category. ... show more

  • Worst filter ever! Don't let the positive feedback fool you!
Size: 1-5 Gallons
The price is cheap for a reason! The first filter I got stopped working within a week, I did a return and replacement through Amazon since it was within the 30 day return period. I got another one thinking the first one HAD to be defective since the rating on this is above 4 stars. The second one died. I wasted so much time with this filter. 2 burned out! I cleaned it very well both times it stopped working. All the positive feedback must be from people when they first get it before the motor completely burns out. If yours stops working it isn't defective, it's just a terrible filter & you'll be lucky if it lasts a couple weeks let alone a couple months. I went with the whisper IQ and absolutely love it. I won't ever purchase this brand again for any of my aquariums and I have multiple aquariums. Be careful because you may get it and think it's a good little filter at first like I did when it's actually working, but I can almost guarantee it'll die within 6 weeks. Then the return window will be closed and you'll be without a filter and you won't get a refund if it's after 30 days. I'm going to purchase a different brand now. ... show more
