Another way to product water lights is to put a luminuos layer underwater, the result are different but looks interesting; in the one i attach i used luminous+ reflective (still the same layout of green wave)
other interesting to say here:
The disc planet are cicrumcentric disc objects with image map shader of snow, low luminosity values and 0.5 opacity
Eclypes blue effect was realized triking the atmo of the planet behind in the way yoo see in attach
