I have used for decades in aquariums and this time even different filters. Currently I run a 800 liter fresh water aquarium with (Increase) many fish. Used the Fluval A412 and an Eheim filter. Therefore, I have a good chance both filters to compare. One advance: the mixing operation is optimal for me. The Eheim filter operates reliably and quietly at a constant flow rate for many weeks. The flow capacity of the Fluval take with me after one week, until it dries completely. This is a common criticism I read in various reviews. This is due to an extremely fine mesh prefilter in the form of a removable filter cartridge. This is easy removed and can supplied with a brush under running water Ruck Zuck be cleaned. This cartridge makes me absolutely amazing clear water, which I had never in operation with 2 Eheim filters. Should I now times a few days do not feel like cleaning the cartridge, the water becomes cloudy due to the many fish quickly again. The cartridge is thus composed not close because the filter is bad. Rather, the Fluval dirt particles filtered out of the water, which are not caught with my Eheim. So one can hardly complain that the filter cartridge needs to be cleaned frequently, because it only serves its purpose. I have now gained a second filter cartridge, which I only sink with a brush under water and then dry free-blowing with a home compressor. It is in this way almost like new again. If the cartridge is sealed simply exchanged and I can then temporally variable clean again. Flushing takes less than 2 minutes in the sink, however caused many mud splashes through the cleaning brush. Here some skill is required. The functions offered by the display I find uninteresting to me and not use them. Therefore, I can not judge about this. For me, a super filter only on the basis of treatment performance and ease of cleaning. The latter applies also to the way of the main filter cartridge. Simply remove and clean. My Eheim filter I have ever completely out of my cabinet fumble which makes cleaning much more unpleasant. I run the filter for more than 1 year and hope with my estimation one or the other to help in the purchase decision. Because the price is indeed a proud .....
