5 star reviewed in the US.   1.My tank has never been as clean as it is very quiet and easy to assemble love it. 2.Actually Silent.Keep the filter in line with your water level and use the blue thing to make to motor not touch the glass and there is 0 noise perfect for a bedroom tank. 3.Nice.I’m sitting right next to it and have to look to see if it is running. 55 years doing aquariums and it’s literally the most silent device that lve had. I have this set on high. As far as quality it’s made very well now let’s see how long it last. 4.it was actually very simple very very well priced for how big and nice quality parts I really like the oil film remover it spins around and sucks up all the food that your fish did not eat. 5. Worth the Money Spent.What I like about it is it’s very easy to assemble and to take apart. The instructions are pretty straightforward. I love that it keeps my tank very clean and clear . It says to clean it out once a week but I have gone longer than that . Still have the same results!! Best thing they ever made because those disposable filters are trash! 6.Coolest HOB filter I’ve had.Awesome little filter for the price! I bought this for my new 3gal pico saltwater reef tank and I really love it.I’m considering getting the larger one for my 10gal betta fish aquarium because it’s doing a great job on this tank and the filter seems super simple to replace.I’ve had it running for about a month and the surface skimmer does a great job of keeping the surface water clean.  EB02:100GPH,0-30 gallon,Small.
