forgive the inexperience with refugiums here. Would it be good practice to include a DSB in the refugium or would that be non productive due to the DSB attmepting to do the same job as that of the algae. Correct me if i'm wrong, the algae uses Nitrates to create its own plant material whereas the DSB converts Nitrate to Nitrogen gas. Would this mean then that both DSB and algae in the same system would result in starving algae or a pile of do nothing sand. Any help appreciated.
