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

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.

Really love this filter! I bought it because I’d read somebody else claim it’s very quiet, and it is. You can hardly hear it running. It does a great job considering its size. I have the filter running on my 4 gal cube & it seems like the perfect amount of flow, but there’s a knob if you find it’s too much/little. I also love the built in motor style, because it feels like much less of a risk for spillage. I was impressed with the quality and thoughtfulness of this design, especially considering it’s only ~$10.

I don't normally write a bad product review. Normally, I just don't buy from the same company ever again. However, I think that this should be under the reviews so that people know. I ordered this item and at time of review, have had this hang on the back filter for 2-3 weeks or so. I woke up and checked and checked on my aquarium only to find water all over my hardwood floor and about 2 gallons of water missing from my tank. I look all over for the source as the water wasn't on the side of the tank or on the sides of the filter. I finally found a constant stream of water running down the electrical cord that runs the HOB filter. Luckily for me, I take precautions and there was no water near my plug. It was leaking where the cord meets the pump at the box of the filter. Buyer beware!! If you don't use drip cords or keep your plug at a higher location, this could be dangerous. If I was less competent this could have caused a fire. I would suggest this product to no one. It only got 1 star because I can't give 0 stars.

Great little filter. I am using it with a nano 3 gal tank and it works well, it's very silent and create a nice water circulation at max flow.The price is really nice too. I would buy it again.

This little pump works fairly well. I have a turtle hatchling in a 2.5 gallon aquarium and it is just enough to keep the water almost completely clear. I would buy it again. It says it's rated for up to 8 gallons, but I don't believe I would use it in anything bigger than a 2.5 gallon tank. Other than that, it's a nice, quiet, filter/pump. The cost was nice too.

This thing is sweet!Tiny, but powerful, and adjustable flow.Mines been running 2 weeks and zero issues.I have a 6 gallon, with 2 small tabletop fountain type pumps for circulation, in addition to this filter pump.This looks so much better and way more streamlined than my Fluval hang in back filter.I paid $10 for this. Can't beat it.

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.

Works great, but splashes water from tank onto surrounding surface.
