What do molluscs use to build their shells?

How do water snails grow their shells?

The shell of a water snail grows along with the body and age of the snail. However, a snail can increase the size of its shell especially the species found in sea water. To do this, the sea water must contain rich concentration of calcium carbonate. The calcium carbonate will help the shell to grow. (Read: Plants in the Pacific Ocean) 11.
