Sending electrical current through growth frames can cause them to grow/regenerate even in very harsh conditions, though I don't know the exact extent of wishful thinking behind biorock building. To my knowledge, the more pressing problem behind coral's sensitivity to external conditions is algae bleaching, which impacts everything from sand production for nearby coasts, to biodiversity and biomatter production in the area.
