NICREW Aquarium Internal Filter, Submersible Power Filter with Multiple Function for Fish Tanks 5-10 Gallon, 53 GPH, 5W

The media could not be loaded. I'm actually pretty surprised by this little filter. I got the one for 2 to 5 Gallon, 40 GPH, 3.5W and inhabe it in a 4 1/2 gallon bowl for my Betta. It works well and keeps the water very clear. It's pretty strong, see my video 🤣 but he seems to like it. I unplug it at night for him just in case. Super easy to install and it's pretty small and doesn't take up much space which is awesome. It sticks to the side well with the little suction cups and even on my curved bowl it holds on well.My ONLY complaint is it said one of the stages of filtration was carbon but I put driftwood in my tank and it's not removing the tannins so I'm honestly not sure if it's actually carbon in there. I took it apart and there is a little bahgy of something along with a spong but not sure. It's definitely not removing tannins I'm having to do water changes until they stop releasing.

THE BEST FILTER I'VE FOUND SO FAR. It was so easy to set up, and it works AMAZING. It's nice to have it running in the background, it sounds like a little waterfall, and I work from home, so it's great white noise.My goldfish were even playing with it! They keep swimming up to the clean water that is being filtered back into the tank.

Using this on anything under 7 gallons may require a little work IF you have a betta. The flow rate on this is superb, but the spray bar doesn't reduce the flow enough to make this really work with bettas. You could add extra fine filter sponge or filter floss in the chamber and simply remove the charcoal cartridge or add a tiny bit in the spray arm, but doing so WILL increase maintenance needed on this thing. If you're using this with other nano fish, mind the direction of the flow and you'll probably be fine.That said, this thing is great for simply polishing the water and adding flow. The only downside for me on this is how often it needs cleaning. Expect to clean this nearly weekly. Not a big deal and it's easy to do, but compare it to the Aqueon 10-20 Hang On Back (HOB-with flow reduction dial-works in a 5 gallon) or Tidal 35 (can also be cranked WAY down to nearly no flow), and I think I'll be using those instead.This is a great filter, but after using for nearly a year, I've decide the less my hands are literally in the tank, the better. With both HOBs, I keep my hands dry and the fish are happier.Again, great filter, but just like with sponge filters and canister filters, your hands will be in the tank.TL:DR, Requires power, requires you to stick your hands in tank, no flow control; consider aqueon 10-20 and Tidal 35 at similar price points for easier maintenance.

Easy to set up, Stickiness works better than Velcro in My opinion, Arrived right on time, very Durable as well. Value is great. You get a fine Product that will keep the water in Your Fish Friend's Home safe and Clean. The noise level is negligible, You can live with it. I use it as a " white " noise source, helps Me Sleep.

Overall not a bad filter. I have one and a topfin 10g angled tank so it’s a bit longer than a normal 10 and it’s still fairly strong. It’s very quiet and compact. It comes clean and works right away. I just wish it was adjustable.

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.

It came super fast earlier than expected was kinda confusing for me to put together but that's cause I over think things lol but now it's easy to put together and easy to clean. Make sure it's submerged fully and leave off for at least a minute before turning in on.

Powerful , not to powerful for my 10 gallon tank but definitely would not use on a smaller tank, 4 stars only because it's not as quiet as advertised, my fish seem to love playing in the waterfall aspect ,I have goldfish.
