Well I finally got my tank up and running on monday. I have a 90 AGA with a 1.5in bulkhead, 1in sea swirl, OR3500 and 200 LBS of pure aragonite DSB. Also you will notice a tiny piece of LR probably under a pound...HAHA. Im still waiting for my shipment of LR from liveaquaria. Anyways, just wanted to here any opinions on the DSB. Im planning on haveing my aquascape be divided in two. One huge pile of LR on the left and one on the right. Then there will be a slanted gap between the two piles in the middle. Sound Good? You guys think there is too much sand in there? its about 3.5in in the center where it dips and about 5.5in on the sides. thanks for looking!
