Trying to find parts is going to be a problem Eheim has always had problems in the American market and switched distributors once or twice now just pulling out completely ..
I heard that deal with cobalt isn’t confirmed yet Eheim must be hard to deal with .. if you look online a lot of stock is out and if you go to local lfs it’s just what they have now they cannot get anything .. my local lfs just tried charging me $49.99 for impeller for 2217
