I am moving up to a 210 AGA Aquarium.I want to use Nature's Ocean Bio-Activ Live Aragonite sand.Which size of substrate should I use it comes in Reef Sand and Reef Substrate?I have the 2 overflows in the back so HOW DEEP should I have the sand bed?2 inches?I do not want any sand getting sucked up in the overflows.I was also wondering I have a Blue Line HD70 pump will this be enough to use as a return pump from a refugium to run through a UV sterilizer and out into the tank through 2 1 inch Sea Swirls?
