LPS (Large Polyp Stony)

LPS (Large Polyp Stony) Corals.

LPS coral are overall more difficult to care for than softies, as they have a calcium carbonate structure, pulling elements such as calcium and carbonate from the water, to build their structure.
You will need to maintain these elements for LPS corals to grow. Water changes will do this at the beginning, but as they grow you will likely need to dose the water to encourage further growth.
