Review: Superb and Inaudible Filter - I wanted to buy a quiet a filter for my son's bedroom aquarium and boy is this quiet! Wow. Standing next to the tank and with the filter submersed I can't hear a thing. I honestly cant fault the filter in anyway. We have a 35l tank and the water is crystal clear for about a month now. Cleaning was easy and the fish are happy. Great product.

## Questions & Answers

**Q: is this good for 28L tank with betta?**
A: Do you have anything else in the tank? And any plants? If so don’t get it u1 you would be better off with a string ray filter stronger and more reliable, my u1 kept getting blocked and just gave up the ghost after 2 months.

**Q: Can i use this as a second filter i am running a 207 at present can i run this with it**
A: Yes, run it at bottom of tank, helps to pick up the crap of the bottom, try to form a litttle dip for to sit in so crap of bottom gets dragged to it, but will need cleaning often.

**Q: is this filter ok in another fish tank thats not fluvel ?**
A: Yes i got it in 2 of my 20l tanks and does a fantastic job, easy to clean and dont take too much space.

**Q: I have a 40 litre tank! Which filter do you recommend?**
A: The u1 should be enough for a 40 litre tank. I'm using it now in a 65 litre tank.

### ⭐⭐⭐⭐⭐ Pump
*by R***B on 12 January 2026*

Good quality pump that is effective and quiet.

### ⭐⭐⭐⭐ Sent EU plug- had to return
*by B***P on 21 October 2025*

Sadly I was sent a unit with a EU plug from Amazon so had to return it and buy one from a pet shop. The filter itself is good this was a replacement from a U2 that wasn't really working. I went for the smaller one as that was all that's needed. Quiet operation and filter is easy to replace. The other one lasted years so hopefully this is the same quality.
