Gathering parts for new tank

I have been wanting another tank for some time now. So after a long time away I am starting over. I spent today digging my rodi out of storage. I changed all the pre filters. It will need a new membrane. I had plenty of di resin. I picked up a used 45gal rimless cube with a stand an eshopps sump and a return pump. I also ordered 40 lbs of dry rock. I am not sure what I am using for substrate yet. I also need to get a skimmer. I have a radium xr15 plus a couple led strips. I hope to get started setting this up in the next couple weeks.
