First part of my statement was just saying I didn't completely understand Albert's explanation and how it tied in to the original question of relocating the rock to the sump that is currently in my DT.
I think the point is that no, there is no advantage, and in fact could be detrimental to add the rock to your sump. You likely won't need it (assuming you add the 100ish pounds to the DT) and it could collect detritus, causing nutrient buildup.
