Bests & Worsts Reviews from Amazon

I maintain aquariums for a living. I have been using Fluval canister filters for more then 20 years now, ever since they were on the 03 series. I probably have about 25 running right now of various generations and sizes. They have had some issues in each of the previous generations, but over all they keep improving and are easy to setup, maintain, and diagnose. Just set this one up to replace a model (404) that was 10 years old and my client was complaining of the noise it was making. Instead of replacing the impeller, shaft, and impeller cover which would have probably helped, we decided to upgrade because of the age of the filter and improvements of a model that is three generations newer. There is a lot of marketing fluff on the Fluval page on what the new features are with this generation. But below are the noticeable improvements for someone thinking about upgrading. -They have made the canister itself more robust by reinforcing the bottom corners, they have improved the aquastop valve opening mechanism (but it otherwise seems unchanged). -The impeller cover seems the same from the 06 series (which has been the best improvement over the old 04/05 series that were always breaking a tab). The new pull out for the media baskets is nice as they all come out and go back in at once. -The filter is noticeably quieter than previous models, its extremely quiet, but not dead silent. I was hoping they would convert over to DC operation on this new generation as that's the route most aquarium return pumps seem to be going. Overall I think this is a good upgrade from the 05 and below series, but if you have an 06 series, you're really not getting too much out of the new model. If you are setting up a new tank and don't have any filter, it is an excellent choice. As mentioned before these filters have some history behind them, and with each improving generation they have became more powerful, reliable, easier to maintain, and quieter. If I am using a canister filter on a new aquarium setup for a client these or the fluval FX series are my go to filter. If I start to see any issues with this new 07 series I will update my review in the future.
