Got a 90 gal display, just added a gyre xf150 (set at 50%). The water movement around the rocks is great and good across the tank. Only issue is the sand blows around. In a couple days it may settle but I've got a question. A little at a time can I add a larger grain sand on top of the existing sand bed without causing issues?
