Ok so I was planning on getting a ro/di so waterchanges are no biggie a ato prob won't be hard and im open to all light fixtures but i'm wondering if when I do a wc in by bow reef if I dump it in the 20 with the extra ro/di water and cured live rock and sand does that mean I got a cycled tank or will there still be lots of die off. Oh any nano skimmers recomended and if I add a 10 g sump is it still a nano
