Tank looks good Bryan, I'm just getting back into the hobby as well from about 25byrs ago but just had fish back then.
I had two 55 gal saltwater with under gravel filters and an ehiem canister filter.
I just started up my rsm 130D and am in the process of cycling (about 9 days).
Started with dry sand, dry Marco rock because of the fear of bag hh. I do like the part about discovering néw things from the live rock but didn't want to take the chance.
Keep wondering if I should add one piece of live to help seed things, anyway congrats and nice start.
