Zeovit in a new Nano Questions

[intarsiabox]

Starting a new nano reef that is going to be mostly SPS with some zoas and acans. It is a standard 29g and is using all marco rock with one piece of LR if I can find a decent piece in Edmonton that actually has lots of coralline on it, all I've seen lately just looks like marco rock that is in water. I was looking to try some of the zeovit additives this time around. Thinking Coral Snow, Coral Vitalizer and Phol's Xtra. I'm thinking sponge power would be a waste of money using Marco rock? Is there any point in adding anything to the system before it is stocked with coral? Any other additives to recommend? I'm just looking for good growth, good color and crystal clear water.
