Try this for the water (i have made this finish from scratch...must be better
than your actually):
finish {
phong_size 220
phong 0.2
roughness 0.001 //or try a smaller value
specular 0.8
reflection_type 1
reflection 0.2
brilliance 3
}
and the interior:
interior { ior 1.33 } //..i think you are using this already
