I'm just about ready to move from my 65g Red Sea Max to my newly built 100g (+40g sump/refugium) tank. I currently have about a 100 pounds live rock in the RSM that I will move over. It also has a 1-2" aragonite based sand bed that I am not going to move over, as I don't like the look of it, and want something easier for sand sifting creatures. Any recommendations on finer white sands out there? And should I buy new "live" sand, or is that not needed if I'm moving this much rock? I really would like to minimize an ammonia spike and new cycle as much as possible as I make the transfer, but that much live sand for a 1-2" bed gets pretty pricey. I would like to transfer has much of the tank's corals, fish and inverts as possible within a 24 hr period. Thanks.
