So I will give you times the negative reports let you in this but please do not quench.
There were problems with these vents was much too big and my jewel vision thanks to the bulging disc on the mounted side much too small. Furthermore, I find that there is no goofy Schraubverbing at the suction and discharge side and everything is just put on it.
What here rather the seller on Amazon concerns:
I find missing here information on the filter material, I'm doing this time for you;). There is 1x Filterwatte. Filter mats 1xgrob + 1xfein, carbon filter sponge 1x -> is my filter goes in person to little evidence to 350l tanks and everything should be there.
Final words. Despite its super filter but you have still a lot to buy.
I bought: cocks 2x for supply and return of Eheim (for easy servicing of the filter), filter media not purchased from Eheim (Keamikfilterringe biofilter media, filter pads for pond filter cut coarse & fine itself is of Eheim my template) and down my vent was slightly modified in the original packaging was not the right one.
Good value I think still ok all in all I came up with Acquisition & extra charges for the extra stuff on 140th
For my father, this filter honestly 20years was never leaking, never broken anything so this filter is already for eternity and the filter structurally one is not forced to buy from Eheim you can because as I have said to decide for themselves whether to buy expensive or accesses cheap alternatives ,
I can only recommend this filter. Also because of the easy maintenance when these cocks has easy and complete the filter super easy handling.
Addendum: Many interested indeed how quiet the filter: The filter is super quiet. In spite of the 4x with me filter sponges inside (4cm thick) are 1xFilterwatte, the clay pipes biofilter. That's twice as much as original supplied. The new connection it is a bit noisy through the air but because you shaking 5min on the filter is then eigendlich everything out on air.
I hope I could help you in deciding to buy this filter ...
