Fast and fully supplied. Unwrapped, connected works. For detailed instructions, filter has priming, very good. The hoses are disconnected and at-the pump head with a Veriegelung without somewhere splashing water. The individual filter baskets are easy to take, thanks to its large volume, it has a long service life. The filter has a lot of power and can be regulated in strength. Important are the small "plastic items" that need to be pressed against the tank bottom, then the filter is also nice and quiet. A very good filter, but actually I also have expected from Eheim otherwise.
