Review: Must have ! - Best in tank filter I’ve had. Bought as original tank filter went down in my 130l , the pros of this filter are - -super quite , hardly any noise -smart looking / blends in / fits nicely -3 different spray modes (top , bottom or middle for gentle flow) So easy to use / setup and for maintenance The water is really really clear with the active carbon in the filter , it comes with ceramic media too which is a bonus Overall really good filter , highly recommend this in tank instead of external canister
Review: Good filters, quiet in operation - Brought to replace a failing one. I find these last a few years and then start failing. I like this filter, it is quiet and does the job well. Needs cleaning about every 2 weeks in my 100L tank.

## Questions & Answers

**Q: Does the whole unit go under water? No spray bar to make a noise? All the aeration underwater bubbles? My filter at the moment very noisy!**
A: its very quiet, just a small hum if you get near it. It has 3 settings, one makes bubbles, the other ones are silent, you dont have to have the bubbles if the unit is under water, mine is just above the surface, i dont like to trail the wire in the water but some people do and the unit can sit in the bottom of the tank, it is large but a few plants will cover it, hope this helps

**Q: Hi does the filer come ready to use or do I have to buy the filters and foam seperately?**
A: Hi Leigh.It comes with the filters and biomax filter media :-) I get my refills from Amazon seller The Aquahut for £11.59 for a 2 pack foam pad, 2 pack cartridge pack and 170g box of biomax. Good value and very reliable seller. Have used them ever since I purchased my Fluval U2. Happy to help :-)

**Q: I have lost the grey stopper that regulate the slow from the top filter. Is it possible to purchase these separately please?**
A: You can use a blob of bluetac and vary the air flow like that.

**Q: Will this filter work if I use it horizontally on its side, rather than vertically? I want to use it in my turtle tank which has a low water level**
A: I can’t see it being a problem. How deep is your water though? This is enough filtration for a 110l tank so if you’ve only got a bit of water in the bottom a sponge filter may be a better option?

### ⭐⭐⭐⭐⭐ Amazing filter top marks all round
*by S***Y on 1 July 2025*

We bought this as the filter we had was not doing a great job water was never crystal clear. Bought the u2 and over night the water was clear. The pictures added to this review are from this weekends water change/aqua scaping. The water got super cloudy due moving the sand about. With in a few hour a noticeable difference. This morning the tank was crystal clear. Out water is dark due to new wood tanens being in the water. But the water its self is beautifully clear. Quiet filter and easy to use. It is quite a big filter. We have ours hidden behind some wood. The three settings for bottom middle or top flow is great to have. Easily removed for filter changes. I cant recommend high enough. You can feel the quality. If you order this get a eu to uk convertor plug as mine came as an eu plug and not a uk one. Wasnt an expensive add. Even that doesn’t take away for how great the filter is
