I'm not sure if you pressed F9 to change the illumination, as it reduces light effects and colors, along with the water. If you did it, try to press again until it's set on the "max effect" mode, where different light sources have different colors, de illumination it's smoothier, and the water will look as you want. If that's not the problem, probably there's no way to fix it (bug).
