NICREW Fish Tank Filter, Internal Aquarium Filter for Small Tank, Coldwater or Tropical Aquariums, Up to 20L Black

Fantastic filter, I needed a new one as the one that came with the tank I bought the filter was extremely noisy so I ordered this one. It's fantastic, quiet, easy to install and offers good filtration.

Was bought for my dads tank but his happy with it and says it works well but smaller than he was expecting

Really good! Keeps the fish in my daughters small tank nice and clean and doesn’t make any noise. Got lots of extra bits to extend the water output. Seems sturdy but have only had a few weeks so far. Not a bad price either

Excellent mini filter ideal for beta tanks cleans the water excellently but you have great control of the water flow to speed it up or dial it back.

This is an ideal bit of kit for a small tank. It was easy to set up and the instructions detailed the different ways of assembly which was helpful. It gives it a strong jet of water and suctions through well, the water has remained clear since installation. Haven’t had to clean but it comes apart easily so don’t imagine I’ll struggle. Only drawback is if you have the water jet too high from the surface it’s quite noisy, but once I got the right placement it’s quietened down nicely. All in all would recommend especially for the price!

I am sharing this video and comment because other users’ comments were very helpful to me as a new fish tank owner. I was not completely clueless when buying this, but their advice helped a lot. It is very easy to use and a very cute filter. Thank you to the seller.

I purchased this filter due to positive reviews for my small tank, but I am very disappointed. Since using it, several fish have died and the water has remained cloudy. I tried various fixes, but only switching to a better filter solved the problem. I would not recommend cheap options, spend a bit more to protect your fish and maintain a healthy tank.

It's ok working when you joint over head pipe it's make good bubbles and water pressure but when you joint liitke pipe with other areengnebts and submerged in water it's doesn't make bubbles just flowing water out. Filterration I think ok because when I seen at bottom of tank that food particles doesn't filered. That actual circulation of water of whole 20 litter tank might take more powerful filterration than this one. I attached here two different pictures that indicated actual filterration unit with overhead parts and other one bottom of tank that you can see food particles wasn't filtered.
