Pro: The material quality is good to very good, as is the functionality (hose connections, commissioning etc.), easy operation.
Cons: Right weak flow, subjectively clearly audible, me too loud operating noise (motor / pump head), high cost of ownership, black plastic lever to lock the hose adapter to shaky / thin plastic.
I expect an external filter, which is designed and designed, that he could be free-standing in the living room / bedroom and that it is whisper quiet. This is not the definite. He is 5 years hunting my most loudest filter, despite various measures (set to foam, thorough ventilation of the filter, I put the filter even in a box with foam for sound insulation, the pump head, I could not insulate this as would be made to measure necessary).
The Fluval G6 costs prof compared to the Eheim. 3 250 more than two times and is it also more than twice as loud (for me in the living room as a freestanding filter is not portable). In addition, the Eheim has significantly better flow (flow at Ausströmerrohr much stronger), despite lower nominal flow rate. Those are numbers on paper, which are often determined without filter mass (similar to Vebrauchsangaben by car). The two filter cartridges in Fluval seem as strong but slowing, Fluval had probably already the prefilter so changed / modified the design.
These above-mentioned problems and the high purchase price are vll. A reason for the eye-catching price decline of nearly 50% for RRP.
A statement about the long-term operation, I can not do. I changed after 4 days on the Eheim Prof 3 250, which is much quieter (s. Review there). Too bad the Fluval would have been much quieter, I would keep it.
So it remains as always up to you if he feels above points as a disadvantage.
Thanks to Amazon, the top service.
