you will want to go a bit slower then that. the tank will need some time to cycle around 3 weeks or whenever the ammonia spike hit 0ppm and the nitrite spike hit 0ppm. Then its safe to do a water change and add a little stock slowly. You may need to add some cooking shrimp (cocktail shrimp) to get the cycle started. Most of the time live rock will not be enough to really get the tank going.
