The pages with my notes are here, and particular aspects, like speed of growth and fragging, are here.
Water flow: not too low, preferably tentacles should be slightly moved by flow, but not swept away, covering mouths.
Flow off for a target feeding. Could be on, but a lot could settle under the rock, and amount should be increased, so tubastreas anyway will receive some food.
I don't have the black stuff on mine and never seen descriptions of that on forums, sorry. Unless these are pieces of decaying food, that stuck between polyps, missing the mouths. Basting in morning (if you feed at night) will help, consider it analog of flossing teeth
for tubastreas.
Necrotic tissue, IMHE, is grey - you can see it in the first link, under fragging.
I have black powder-like stuff, but on bottom of the tank, not on corals. Tend to think, that this is excretions - it much smaller, than planulas. And this is not sediment, produced by liquid phosphate remover - it was before its use and after.
Tank is bare bottom, nothing, but sun corals, all is quite visible.

There are photos of sun coral planula on the web, likely foundable by search on sun coral babies. Here is my T. faulknery (ID?) spawning:
