I have an 11 gallon salt water aquarium. I'd like alot larger one, but I don't have the space.

I have 18W metal halides. The one that simulates morning & evening is 5500K. The daytime one is 7100K.

My question is how long should the morning & evening lights be on & what is the total time my aquarium should be lit in a 24 hour period to stimulate optimum coral growth ?

Thanks.
