I am keeping this guy in my "lets see how you do" tank which is a Cube that has a koralia #1 in it and has a sump plumbed into it. The sumps waterflow I'd say is light... Though it can move the sand. The koralia however easily moves the sand and everything else in the tank at a slow steady pace. Would this suffice? The lighting overtop is a 100 watt 6500k, a 40 watt Actinic and a 40 watt 10k. The Cabbage will be only about 4 inches under the water on a shelf.
I also use reef crystals to offer better Calcium to my tank, as well as when needed use Reef Code A and B.
