I'm all for keeping nuisance algae and pests out of your tank, but there are helpful hitchhikers you will want in your live rock or refugium. The best place for copepods, amphipods, and other small benthic creatures to thrive is in live rock or macro algae in the refugium.
I would recommend getting live chaeto or other helpful macro algae in your tank was soon as you cycle. They absorb nutrients in the same ratio as nuisance algae and can get a foothold to take over that ecological niche in advance of pests.
If you use healthy macro algae from other reefers, you'll be well on your way to culturing a nice ecosystem of pods and small benthic critters. If you need to boost that as a food source, I'd recommend buying pods in bulk or learning to culture your own.
We setup a very active refugium during our initial tank cycle that has been a big help in nutrient export and providing a home for pods, snails, brittle stars, and other critters to reproduce. We have a breeding pair of mandarins, so I still supplement the pod population with live pods every month or two.
