So I have a 90 gallon display tank, mixed reef with a little bit of everything. The tank is pretty scratched and I think I want to upgrade. I'm going to put all my live stock in the basement since I have a 75 gal frag tank, the question is if you had the chance to start a brand new DT how would you do it? Use live rock you have? Get cool new dry rock? Also what's a good DT. I've been looking at DSA rimless.
