Ok so I have started an SPS dominant shallow reef. Tank dimensions 84" x 24" x 16" deep. Lighting Hamilton Cebu sun MH T5 combo. Filtration 100# at least pukani, and some shelf rock, and 3 marine pure 8" x 8" x 4" blocks in sump. RO ELITE 220 INT skimmer, 12" deep sand bed in sump, and I run a filter sock on the line into skimmer section. the drain feeding deep sand bed is unfiltered. ALK is right at 8DKH, calcium 400, magnesium 1250. Acros seem to be coloring up good and growing, but I want to be sure I am doing things right. What would you recommend for my tank? Thanks. I will add photos soon.
