Science question, please help if you know. If they don't make them out of phosphate, can you please tell me what they do make them out of?

The skeletons are mostly calcium carbonate.
Here's a web site that backs it up.

Calcium carbonate is correct. And the carbonate part is important since that contains carbon from carbon dioxide that used to be in the air. It is a carbon sink. A much better one than a forest since the skeletons do not decay and release the carbon dioxide back into the air after the coral dies.
