Heavenly Damsel,
Interesting info. I have not read eric's book but have read other info claiming that lighting in a home aquarium is only part of a proper diet for corals.
In fact a while back I read about a public aquarium that relies mainly on feeding the corals kept (all types, sps, lps, leathers, polyps) and the lighting for the corals is second priority. Of course they were using an open system which means fresh saltwater is constantly being pumped in.
I guess the biggest problem with feeding corals in a closed system like our home aquariums would be the ability of the filtration to be able to handle the additional load of all that food.
I find this topic very interesting and believe it will change the way we look at the setup our aquariums in the future.
