Who was it that lived in Surrey and had all the wonderful Acropora that he was keeping under NO fluorescents? His coral grew slowly but it was beautiful. I think there are exceptions to most if not all the rules, myself, I had best luck with MH's, even my derasa picked up nicely with in a couple weeks of adding MH. Personally I'm a firm believer in MH but I've been wrong before.
