Hi - I'm about to set up a new tank, its 5' long and 18" high (2' deep). I'm utterly confused over lighting. I don't want MH because of the heat & running costs, but I do want a tank with fairly good lighting so widen my coral options and to enable some of the lower light loving clams. Kit I currenly own are two dual T8 strips and two 55w T5 compact units. Ideally I'd utilise these in the set-up, but its not essential. I'm also hooked on the shimmer effect of the LED's so I'd add a couple of these for definate. Am I right in assuming that a couple of the Aquabeams and 4x t8 are not going to be sufficient for things like torches and hammerheads?
