Most of the pods we have are detritus feeders at least as adults. Many pods however have a naupli stage in which they consume phytoplankton versus detritus.
If you want to breed/feed your pods live phyto would be the way to go in my opinion.
Your soft corals and clams will like it too.

I wiped out most of my pod population by dosing magnesium (Kent Tech-M) to get rid of Bryopsis. The Brypsis went away but with it about 90 percent of my pod population (something to think about - a lot of people think adding another pod eating fish is the only way to wipe out pods -it's not)

I've been dosing live phyto (mainly for the clams actually) and my pod population is bigger than ever.

I would focus on adding pod foods over adding more pods.

Ultimately I wouldn't rely on pods 100% though.
I like having a back up plan in case something causes a shortage. None of my mandarins go in the display tank until they are solid on eating frozen food. (that's of course especially crucial for me since I have a pair. One slightly hungry mandarin is not problem. Two hungry mandarins will constantly fight with each other over territory)
