Not just survive but thrive(poor choice in wording here). Corals do not need to be directly fed unless they are NPS plain and simple. While they can benefit from direct feedings, they do not NEED it(the whole point of this thread actually)
To your point about planktonic soup, AKA NSW. Again feed the tank and create the planktonic soup as I already posted above. The entire point of my post was to feed the tank, not the fish.
If you need to feed your coral, then you need to up your bioload. More fish = more fish poop = more ammonia = more coral food(Your corals actually prefer ammonia over N and P).
