How do you care for a coral reef?
To ensure that you care for your Coral Reefs, You need to ensure you have the following this from the Coral.org site. I did some research of my own to answer this question properly as Coral Reefs are VERY important to the world I have found. Sunlight: Coral needs to grow in shallow water where sunlight can reach them. Corals depend on the algae that grows inside them for oxygen and other things, and since this algae needs sunligh to survive, corals also need sunlight to survive. Coral rarely develop in water deeper then 50 meters. Clear water: Corals need clear water that lets sunlight through to survive; they don't thrive well when the water is opaque. Sediment and plankton can cloud water, which decreases the amount of sunlight that reaches the zooxanthellae. Warm water temperature: Reef-building corals require warm water conditions to survive. Different corals living in different regions can withstand various temperature fluctuations. However, corals generally live in water temperatures of 68-90° F or 20-32° C. Clean water: Corals are sensitive to pollution and sediments. Sediments can settle on coral, blocking out sunlight and smothering coral polyps. Pollution from sewage and fertilizers increase nutrient levels in the water, harming corals. When there are too many nutrients in the water, the ecological balance of the coral community is altered. Saltwater: Corals need saltwater to survive and require a certain balance in the ratio of salt to water. This is why corals don't live in areas where rivers drain fresh water into the ocean.
