Welcome to Canreef! Enjoy the tank build up! You will find loads of useful information here!
Just my opinion, but you will achieve exactly the same result by adding one or two small pieces of live rock to your Marco rock! (booster card not needed) Given time all live organisms will spread and multiply into your Marco rock (Great choice by the way!) That is the best part is watching all the little critters start to appear!
Have fun!
