And yet another thing: This is how I'd do the water-sphere:

sphere {0,1
  ball_at (2,3)
   texture {
    pigment {rgbt  <1.0,1.0,1.0,0.98>}
    finish{
      diffuse 0
      ambient 0
      specular 1
      roughness 0.0001
    reflection {0,1 fresnel}
    conserve_energy
    }
       normal { agate 0.3 scale 1.3 }
  }
    interior {ior 1.33}
}

No need for the "glass.inc" at all, proper Ior for the water, as well as
reflection. Specular and Phong are two models for the same thing:
Highlights, so I'd go with just one of them. Since the rgb-color is <1,1,1>
I'd go for high transmit instead of filter.
