Easy to maintain and easy to clean. It’s very quite hardly can hear it.

Best external filter. Had a couple of fluvals and much prefer this one. Possibly will be buying another one for my 90ltr

Bought this in an emergency after my old Fluval 403 failed, had a delivery problem but it turned up unexpectedly after saying it would be delayed for 5 days, on the upside customer services were very reactive, it's a good bit bigger than the Fluval, build quality is excellent bar the baskets which are a little flimsy but work, the included media is junk but hey it's free, ditch the bio balls, no use here, you can stick some of the ceramic media right in the bottom below the baskets then get some pond sponges, the three grade ones and cut them to fit the bottom basket, there's room to get one of the included white mats on top, the other two baskets you can fill with your favourite media, I like Alfagrog, that's it. Runs quiet, flows better than my Fluval, the way the pipes unclip is excellent and the included pipework more than sufficient. Totally recommend.

Decent at it's function and build quality seems fine it's just noisy, personally wouldn't recommend if the aquarium you will be using it for is in an area you will be spending a lot of time (i.e. living room/bedroom etc) because the noise is very noticeable.

I rarely write reviews, but this time I want to leave 5 star rating. My watermark never was so clean! I have 2 catfishes, they poo alot!!! The bottom on the aquarium was constantly dirty. This filter somehow can absorb all poos leaving the gravel clean. Really recommend. I have 1000EF model for 125 litres watermark.

NOTE READ LATEST UPDATE AT THE BOTTOM BEFORE READING THE REST OF THE REVIEW AND DO NOT BUY THIS PIECE OF JUNK!!!So firstly the issues, the pump could be quieter, it has a general hum that is not as quiet as I expected, I haven't housed it in the cabinet it is due to go in yet and I am sure this will reduce the noise but it is still quite noticeable.The bend on the output pipe is not adequate as the spray bars wont sit in the water ( I have a jewel 180 litre and the max water level marked on the tank is lower then the lowest setting for the spray bar) This is pretty stupid as a bigger bend by even an inch would solve this and if you wanted it higher you could just have a bit more bend protruding from the tank. The pipes are very stiff and hard to fit and wont push far onto the fittings but I am hoping they are on enough to stay on. Everything could be a bit longer, the pipes and the electric cable. Lastly and most frustrating, the second video on here showing you how to install is, I am guessing for an earlier model as none of the parts in the video match the parts in the box! It doesn't come with 4 suction pads as stated, it comes with two, almost all the fittings are different to the video which is not only miss selling but makes it harder to work out how to set up and install. So now the positives, It filters 1000L per hour and is fairly big and solid, with plenty of scope to modify the filter media, its only £49 with free deliver and came the next day, so you do get a decent bang for your buck once it is up and running. I want to give it 4 stars, but as I didn't get what is in the video and its not as quiet as I hoped I can't give it more then 3 stars, but hopefully it will be just about fit for purpose and is far cheaper then other brands and models with a similar spec. If I could give it 3 and half I would!EDIT 30.06.20 I have upgraded this to 4 stars, as now I have let the pump run for a few days it is far quieter then on set up. It may have had some air trapped or just needed to settle in but I am now happy with the ambient noise level.UPDATE!! 20.09.20 Currently in the process today of ripping this filter out and replacing it. In the last 3 months it has totally stopped twice and it is a nightmare to get running again and a nightmare to prime, when I have been able to get it working again the output is barely a trickle and is so bad I have had to have another pump running just to get some water movement and air in the tank. I also had a professional pool and pond service agent look at this and he couldn't get it to perform either, so I know its not me. AVOID THIS JUNK AT ALL COSTS!! DIDN'T LAST 4 MONTHS!!!

The media could not be loaded. The set up is easy as anything (I did have to soak the hoses in hot water like the video says, but worked a treat)The pump itself is fantastic, you can literally see it suctioning. My old filter broke and I replaced it with a small one I had to keep the water moving but it wasn’t suitable for the size tank so there’s quite a bit for this one to clean up.The noise is minimal, a slight humming and the running/moving water.The only thing that’s not so good (and this may have been in the description and I missed it) but the clamps that go on your tank to keep the inlet and outlet in place aren’t exactly brilliant for my sort of tank due to the angled edge, as you can see from the image, they’re barely gripping. So they could do with being a bit wider and longerOther than that, money well spent so far

I took up the hobby about a year ago and my original internal filter stopped working so I replaced it with a similar product, I find the new filter looses water flow within a day or so I have a 180ltr tank planted and a fair few fish so it does create a lot of waste. Taking advice I was encouraged to increase the capacity of the filtration and decided to take a punt with an external filter. Doing some research I kept combing back to this filter as it has some great reviews. I have set it up this morning and the set up is straight forward and easy to install. Running out the pipe work and putting it in the tank was straight forward to do although the instructions are maybe not the best with time and logical thinking it’s easy to work out. As I have learnt taking time to install and run pipe work wires etc around the tank slowing down and taking a bit longer leaves you with a neater job. I did slip up and forgot to measure the unit so found it does not fit in the cupboard but no drama it’s set up at the side and hidden by some carefully placed house plants. The pump is quiet and water flow is excellent.All round extremely pleased with this and looking forward to the future of using this pump.
