Copepods Gone Wild

[Liquid360]

I've got an old 30g tank which I've kept running as an isolation tank. I've also added quite a few copepods. Now the population has exploded. I feed them phyto on a regular basis.
Question: anything else I should do?
And is it a naturally regulated system insofar as population density is concerned? Or should I removes some of them?

You could sell them to people who have mandarins. Or, you could add a mandarin. Great looking fish to keep.
