Small-polyp hard corals, also called SPS corals, are very popular with experienced saltwater aquarists. Although these corals require certain conditions and water parameters to thrive well, these hard corals build an internal calcium carbonate framework that forms intriguing shapes and makes up most of the natural reef structure. Due to their skeleton, SPS corals require a consistent level of calcium and alkalinity to generate good growth. They need lots of light and flow to reach their full growth and color potential.
