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.

Sent EU plug- had to return
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.

Good Filter but Inconvenient US Plug for UK Purchase
I ordered this filter from Amazon.co.uk, expecting a UK plug. Unfortunately, it arrived with a US plug, which was inconvenient and required me to purchase an adapter. Despite this, the filter performs well. It runs quietly, keeps the water clean, and is easy to set up. If you can deal with the plug issue, it's a good choice. Just be aware of the inconvenience for UK use.

Had one of these fish tank water filters before, it was about 4 years old before it packed up , and that's working 24/7,so I think that's pretty good.

J'ai commandé le Fluval U1, car mon ancien filtre Fluval (que j'ai gardé 15 ans) m'a lâché. Le filtre est très silencieux, notice en Français avec images d'illustration. Entretien facile, fournis avec une mousse filtrante. Prix un peu élevé, mais produit de qualité. Je vous le recommande.

I have both U1 and U2 filters and they are awesome. Nearly silent. Huge upgrade from HOB style.
