I will say this--- you don't have to feed an SPS dominated tank to be very successful, and in fact, I don't recommend it to inexperienced hobbyists like the OP ( not a slight, but just the reality that you are still in the beginning learning phases of the coral reef game).People were keepiing full blown Acro tanks long before all these wonderful new coral feeds were available ( and I do think some of them are very good).
BUT, they are not necessary for success and until you have a solid handle on water quality and general husbandry, I think they should be avoided. Just feed your fish well. The corals will be fine.
