In a tank that was started with good quality and cured live rock and running a fuge,you've got pods.They just need time to and food to expand their population.
90% of the time,when you buy those packaged pods,all you end up with is a little bit of water with a strand or 2 of cheato in it and a few dead pod bodies.
To help what you already have expand,feed a little phytoplankton a couple times a week.
