do you need calerpa in the sump?Since the unit kills nitrates and a phosban reactor can take care of phos..I would imagine there isn't a need for calerpa or chetto in the sump.Maybe just some bioballs for bacteria to grow but now is there a need for calerpa in the sump since the Rowa phos and a denitrate reactor can take care of a reef tanks 2 most deadliest enemies.No phos no bad algea no trates no dander to corals bleaching or dying.
