So far so good...quiet and crystal clear, what more can I ask?
The Fluval 206 canister filter gets good reviews and so far I am pleased with it's performance. I have only used it for a little over a week, but it is quiet and keeping my water crystal clear. I have had zero leaks, it was easy to prime and set up, too.At first it was quite noisy and I was a little perturbed, as I was expecting it to be very quiet. I research and research products before purchasing; I had read about how to get this filter to run quietly. Air in a canister filter can make it run noisy. There are a couple things one can do to help eliminate the noise and air from the filter after start-up. One is to turn it off, open it up, make sure the impeller is properly seated, close it up and turn it back on. I read that turning it upside down can help eliminate air as well. I can't turn it upside down because it's in the cabinet below my tank, so I picked it up while it's running, and turned it over as far as I could, to the left and to the right, about twice a day for the first couple of days. By day three it was running very quietly...wahooo!I have never had an air pump, but am adding one with this filter due to the water outlet being 3" below the surface. The spray bar kit may help but I think the addition of air bubbles in my tank is going to add to the over all look of my new tank.April 24, 2016 - I just cleaned the filter for the first time since start-up on 3-13-2016 and it was not very dirty at all. I rinsed out all media in the water that came from the canister, cleaned off the bottom of the pump head and put it back to work. My water is crystal clear and the filter was hardly dirty after almost 6 weeks of use from the date I added fish. Granted my 37 gallon aquarium is under stocked with 8 Zebra Danios, 3 Buenos Aries Tetras, 2 Fancy Guppies and 2 small catfish, but I'd rather have it under stocked than over stocked. I am impressed with this filter system.July 4, 2016 - I just did a water change, but haven't cleaned the filter since April 24, 2016. My water is crystal clear and the pump is running near silent! It's an awesome filter system. I will give it a thorough cleaning soon. Make sure you use the water from the canister to clean your filter medias. Everything else I rinse in warm tap water and so far all is well.
