FLUVAL U1 Internal Filter, 55 Litre

Product Information

Overall I am somewhat disappointed in this filter, being less powerful and reliable than I had anticipated. The look of it is quite nice from the stingray filter I previously had, although it doesn't help when my cycle almost stops due to the filter inability to maintain output. The Fluval U1 Internal filter has an adjustable flow to ensure the filter meets the needs for different aquarium environments, minimum output creates a gentle flow perfect for planted aquariums whilst the maximum output increases circulation and oxygenation.

So what’s changed? The first ‘tweak’ appears minor, but is actually essential. A tag on the front of the filters, as soon as you extract them from their boxes, shows you how to remove the impeller and give it a clean. If the pictures are confusing, then you can always scan the QR code instead, and watch a video about it. Accessing the impeller for maintenance is a doddle. Anyway I am now making use of my other power head as a bubble machine but that is for another thread on how I converted my power head into a bubble machine with no need at all for a Venturi Valve of any kind and one that has a proper flow rate. Large pallet items like aquariums are deemed delivered successfully with no damage once the the driver has left the property. If a report of damage is submitted after the driver has left we may be unable to assist with replacements. We recommend refusing a damaged delivery, this is the fastest resolution.The Fluval U1 is a compact and versatile internal filter for aquariums up to 55 l. This small aquarium filter is very comfortable in handling. The outflow can be regulated and it can be mounted vertically or horizontally in the aquarium. Thanks to the flexibility in the positioning of the filter, it can be used as a primary filter in smaller aquariums or as a supplementary filter for larger aquariums. Their unique ability to be placed at the bottom of your aquarium makes it ideal for low water levels. The removable central core allows use of chemical or biological media. So as I bought my girlfriend a Fluval U2 filter to replace this Stingray 15 on her tank and all has gone well with that filter, I was looking at buying a Fluval U1 filter for my tank (40L). I gave up on this now because with the crap flow this thing produces it does not matter how good your venturi valve is ( and mime is now how a venturi should look) it is never going to produce any amount of good bubbles. However upon looking through this from what I have initially found appears that the Fluval U range is "3 Stage filtration" bar the U1. The U2/U3/U4 all using 3 stage filtration however the U1 appears to just use a sponge. About the smallest filter I think I've experienced (excluding simple box filters of old) is the Aquaclear Mini (now called the Aquaclear 20) I'm currently running on our quarantine tank. I find 3 (not always present but potenially there) noise problems with this filter: first, the impeller and shaft are not as high quality as you'd find in an expensive filter and can get noisy over the years; second, its an HOB, so there's the built-in waterfall noise that you can only escape right after water change time; thirdly, there's the little plastic top cover, which can hum and which of course you could choose not to use or to modify I suppose. Of course, the simple rectangular media box gives maximum flexibility, which is what makes all these ACs be contenders in the first place.

The adjustable 3-way flow control feature lets you position the water flow output to meet your specific needs. The Top Output setting provides maximum circulation and oxygenation, the Integrated Spray Bar setting provides a gentle, even flow for planted aquariums, and the Bottom Output setting is for deepwater agitation. A venturi valve that produces les bubbles than a fish (even took the bung out the end and even took the valve off the airline inlet valve and yes it was above the waterline) I'm trying to get to the bottom of this, I have currently a stingray 15 filter and want to replace it I have an Aquaball filter which is too noisy and a cheap Aqua Flow 1 filter which I know nothing about so don't want to use it as I don't knows its capabilities. I like the ceramic media and as I have found it to be very successful find that the Fluval U range is very attractive because of this property. However now that I've just noticed the Fluval U1 is only a sponge it feels like it loses ALL of its great points about it. im Inneren der Filterpatrone kann der Fluval Clean & Clear Filtereinsatz oder andere Filtermedien eingesetzt werden

It works great up to the point the bottom of it starts to blog up, at that point its pretty much just a powerhead as it does nothing but push water around bypassing the sponge! Interesting thread and I'll be interested if more results get posted. The problem of finding high-quality small filters has seemed to hang around, at least from my reading. Internal Filters are an excellent option for small to medium sized aquaria. They are simple and easy to set up, they sit just inside the aquarium itself meaning they can be easily installed into any fish tank, with no troublesome pipes and hoses. They will also work well as a powerhead for water circulation, with the added bonus of the extra filtration. It is worth noting that you should clean your filters impellor every couple of weeks to ensure it is functioning normally and keeping the water moving around the tank. U series underwater filters offer superior water purification, movement and aeration capabilities and have been designed for use in both fresh and saltwater applications. The Stingray is plagued with problems and it seems that if I just look at the filter something goes wrong with it. I've had to take it apart and mess around with the motor/impeller about 5 times in the last week as the case doesn't seal properly from brand new and allows sand/plant and other debris to enter the filter by bypassing the sponges.
