If you add a centrifuge harvested microalgae to your system you can add large quantities to both your refugium and main tank without any negative affective. Centrifuge harvesting removes all the nitrates and phosphates from the growing media, so you don't run into a problem of adding nutrients and creating an algae bloom in your system. The amounts of nitrates and phosphates in the actual microalgae are negligable.

The more free floating microalgae you add to your system, the more copepods and other zooplankton you will end up with in your system. Its the bottom of the marine food chain, feeding everything else up the chain.
