Filter for large aquariums (1000 liters) ... Unfortunately, a plastic part was already broken before unpacking (the one which fixes the hoses on the aquarium tank). Since I do not too much trouble to send back the whole thing I have found another solution for fixing. The filter makes almost no noise, is dense, easy to clean and works so far properly. The filter performance is acceptable ... well a larger filter can not get except in the pond technology. Compared with other filters of this size FLUVAL is priced quite OK .. .würde it 5 stars if the plastic part could not have been broken ... Thank God it was not a very important part of why not dramatically)
CONCLUSION: Good uncomplicated filter, easy to clean, for larger aquariums, making almost no noise, is tight and I would buy the filter back
