light required by diferent corals

[StirCrazy]

do you know which book might have it in it Victor? I am getting the bornman(*sp) one "corals". I bought the julian sprung (as it was highly recomended) and it has a scale out of 1 to 10 for how much light a coral needs but it doesent define the equivalent of the scall anywhare so all I can tell from it is one coral needs more light from another.
