Finally got around to adding sand. For this setup, I went with Caribsea’s 1-2mm grain special grade, as I prefer my sand staying put or at the very least not get blown about by the flow in my tank. The still relatively small grain size will mean while it’s not the finest substrate it’s also still a viable habitat for sand-dwellers such as gobies and halichoeres wrasses.
