Now add some nice seagrasses, say Halophlia in those open white sand areas.
Add a bit more current as those and the other things fill in more.
Need a little different sediment for that, but could be done with water column dosing if you are careful.
BTW, no need for the vodka, with plants you have plenty of organic carbon.
Good Bacteria growth + good coral growth+ plants/macro algae growth= little NO3.
In many red mangrove regions that are mature, sponges and various root specific algae will grow on the roots, every bit as impressive as a reef, and often the same no#'s of fish.
Sea grasses grow right outside the shaded zone. Always on my list of places to see when I go to the ocean.
