I'm trying to get a realistic water texture.
Relevant Files Are:
http://cg1.org/scene.pov - Main scene file
http://cg1.org/water.pov - The water
http://cg1.org/povray.ini - Settings used to render
http://cg1.org/render.png - What I get when I render
The problem is readily apparent in the render, namely the blue and white
specks on the water surface. These do NOT occur with a black sky, but I
can't for the life of me figure out what's causing it.

You are using fresnel reflection (as you should for water), which peaks
when just grazing the surface. The white specks are simply reflections
of the horizon. My suggestion is to dump the fog and use something more
realistic. A finite sky helps, in reality the sky and ground are roughly
spherical.
Also, use rgbf < 1, 1, 1, 1> for the water pigment, and color it with
absorbing media or interior attenuation. This is much more
realistic...water is colored by its volume, not by its surface. Doing
this will let its color be affected by the depth of the water.
Oh, and work on your indentation scheme, it's kind of...random.
Consistent indentation greatly improves readability, look at the code on
these groups for examples of common indentation styles.

Update: Antialiasing helps the foreground, but the background is still bad.
