NICREW Fish Tank Filter, Internal Aquarium Filter for Small Tank, Coldwater or Tropical Aquariums, 20-40L Black

A good filter for my goldfish tank. 3 weeks in and my tank is still very clean. It makes a lovely sound, and has a strong flow. Very functional, suction sticks well to side of the tank, waters clear, happy over all.

I bought this small filter to use as a powerhead to circulate CO2 to an area it was not previously reaching.The build of this little filter for the cost is excellent, it even comes with a spare impeller, something much more expensive filters don't include.It's almost silent and feels very powerful for it's size but I haven't used the spray bar or any other connections as I don't need them.I imagine in a nano set up you will need to use the spraybar supplied as without it the jet it creates would be too strong and there is no flow adjustment.

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

Works great

Bought in April and wanted to wait a little before reviewing, the pump worked brilliantly at first for the first month since then it’s become very loud and is not filtering as it first was. It has been cleaned regularly but has definitely reduced in efficacy. Shame as it was a great little pump to begin with and was very happy with it to begin with.

The media could not be loaded. Excellent mini filter. I'm very impressed by price and quality. It really does pack a punch for such a small item. Was initially worried it was too big for my guppy fry of 4 weeks however pleasantly surprised they were very safe and not at risk of being swept into the filter itself. Has kept tank lovely and clean needing less water changes. I was considering getting an air pump but honestly its not needed as there is plenty of air being pushed into the water. I would buy again.

Great pump easy to put together fish loves it.

This filter is very good, it's small but powerful. The size of it fits perfect in my 16L tank, it's quiet and doesn't make much noise at all which I like as it doesn't disturb me too much. The most noise it makes is a really quiet humming background noise but barely noticeable.The only negative thing is that it is very powerful so it moves my sand substrate around a lot, to avoid this I have placed my filter horizontally in my tank and now it is completely fine. The filter itself has suction cups and they are very strong when stuck to the glass, doesn't move at all.It's very easy to set up and install. Another good thing is that this filter comes with a filter sponge so I didn't need to buy that separately.
