@Jeroen,
I see your problem, well there is a pretty easy solution, duplicate the scene and rotate it to pretend to be the mirror, under the water, and alpha it all down a bit.
This is a standard trick, used by many, and you are only repeateing that which already exists so it is little extra work for you and B3d.
But the difference may be well worth it - try it and see.
:)
