Ok, I have the scene set up, but I want to get a good media for the water.
It should be slightly green and I want to see light rays casting down from
the sun.
I have tried, but I just can't get the hang of it.

Use scattering media type 2 or 3 together with absorbing media and of course
faked caustics.

For starters, try:
media{ scattering{5,.01 extinction .001} method 3 }
Don't forget the 'hollow' keyword in the object block; it's so easily
left out sometimes.
Nice water, by the way. What happened to your height_field, though? It's
got some strange artifacts I haven't seen before. What color depth did
you use when making it?

Thanks.

I used a GrayScale TGA and I agree, I am NOT happy with it.

Hmmm I tried that (media{ scattering{5,.01 extinction .001} method 3 }) and
the image took 2 hours to render and was totally white. :( I tried changing
the media settings, but I just don't get it.

This is much better...
interior{
ior 1.33
media{
samples 1,1
scattering{3,rgb<0.5,3,1>*0.001 extinction .01}
method 3
}
}
