Using the graph provided with the question, we are able to find that that for a concentration of 270 micromol per kilogram, the calcification rate is 20 mmol calcium carbonate per meter squared per day.
Using this calcification rate,
30 = 20 * 1 * days
days = 1.5
The deposition will require 1.5 days.
