NICREW Slim Aquarium Filter, Quiet Fish Tank HOB Filters for up to 5 Gallon Aquariums, Adjustable Flow, 42 GPH, 3W

This product is one of the worst products I have bought. If you need my evaluation, I will give it a bad evaluation because it broke down in the first week and when I started using the product, it was very hot. I do not advise people to buy it and I advise them to buy any other product.

Stopped working in the first 3 hours of use

Great little filter. Effective and silent. Unfortunately stopped working after a week and I followed all instructions precisely.

Very disappointed. The product that I received came with a broken motor propeller. There’s a lot of visible deep scratches in the surface even though it was well packaged (Product box with bubble wrap within another box). It seems I was given an already used item.

This filter works perfect for a little Top Fin 3 gallon tank. I have a small tank set up for Corydora fry and needed a decent filter with an intake pipe. The filter that came with the aqaurium was trash, and I did not like it. It pulled from the bottom and kept sucking fry up. The first replacement filter that I got did not have a place for carbon or any type of sponge. This one is seriously perfect. It has a carbon cartridge with a sponge and also a sponge filter for the intake. It helps pre-filter AND keeps from sucking anyone up. The replacement cartridges are not expensive (6 for $9.99 or 12 for $14.99). It is very easy to clean and does not make any splashing sounds. It has a big enough area to add your own media, if needed. The carbon keeps everything circulating to avoid any funky smells. *I just put it in before taking photos, so the tank is not the cleanest.

I had to replace my filter that I got as a kit because it was way too loud. I was apprehensive about this one because it was a good price, but it is the best thing I’ve bought for my tank! It is truly SILENT and it has a great adjustable flow. Very easy to use ans set up. Lots of room to add filter media

This NICREW filter is pretty decent. It's small and doesn't take up much space in my tank, which I like (I have a betta named Bubbles, she loves it). The filter does its job well enough, keeping the water clean and clear. I haven't had any issues with the flow being too strong or anything, though sometimes I wish it was just a LITTLE stronger, you know? Anyway, it's easy to set up and use. (I accidentally put the sponge in backwards at first, but it still worked fine). It came with everything I needed, so no complaints there. Overall, this filter is great for small tanks like mine. The adjustable flow is a nice feature too, although I don't really mess with it much. And hey, if you need to clean the media, it's super easy and quick to do. You can't beat that! Definitely would recommend this one to anyone looking for a reliable and quiet filter for their small aquarium.

So far so good! No issues with my guppies (even baby ones) being sucked into the filter or anything. Easily adjustable for your fish needs. The fish are loving playing in the water stream actually! Very quiet operation unless water level gets lower. Top water up and super quiet again.

This little filter is great but if the sponge gets clogged with plant matter/ fish poop it will over flow and leak so filter maintenence is important.
