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

Doing perfect job for the litre you buy for. Nice power and cleaning the aquarium . A lot better than other small filter for the prices that i have tried from local pet shops. Doing some noise like other reviews saying but its like raining so fine by me . Plus you can push it all inside water or change the outlet and noise gone .

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.

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.

It’s quite well made I use it with the spray bar. It worked straight out the box. I put it in an 60 litre tank and it ripples the surface and helps with circulation, probably not a main pump. It strips down to clean easily and my similar model lasted five years. Comes with a spare impeller.

It is a good filter, got many attachments but does have some issuesThe bubbler doesn't bubble. I cannot work out how to get it bubbling, let's out 2 or 3 then it's doneEvery single time I clean out the impeller it just gets louder and louder. Used tips from YouTube such as Vaseline around it to smoothen the motion. Makes no differenceAlso every time it's cleaned the pressure reduces. I have the tube with the holes going...after month 4 the water is only trickling out 2 holes whereas it was flowing nicely from all 4 beforehandThe water out the end of the tube no longer goes against the tank glass before going into the water, my fish did enjoy this motion of the water but I can't seem to get it backThis is a replacement filter and it seems its not a fault, but just how the filter is builtIt is good but only for temporary basis.Other than that; the company does have good customer service with quick replies

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.

Good fish filter.

The media could not be loaded. The filter is tiny, but powerful. I wish there was a way to regulate the flow. That’s why I placed my heater in front of it to sort of split the jet in two.Overall 4 stars, just because you can’t tune it down and because it’s loud. Tried to remove the carbon casing and try it out without. A bit more silent but the vibration noise came back after 5mn…. Can’t sleep with it being this loud
