You will need to supplement calcium with ANY stony corals. They need more than comes in the salt mix once they start growing. Three methods of doing this are: for small tanks up to 30 gallon---hand dosing; for medium tanks, up to 100 gallons, kalk; for big tanks, calcium reactor.
All tanks are different so be careful about blanket statements attempting to tell you what you MUST or NEED to do in this hobby.
Amen brother. Also, over the years I have noticed a coorelaion between large post counts and extreem (I think "bad" is too strong of a word) advice. I think a person who has 10,000 plus posts, by nature, has an extreem personality and would be inclined to give advice that may be true but is not practical.
