Corals cannot flourish with opaque water. With this, they need clear water for them to get sunlight to do well. They also need warm temperature specially the reef-building corals.
There are algae, corals, seaweed, etc., etc.,etc.
They are fish tanks that have ocean water in them. The ocean water is almost always synthetic but can be real. People keep salt water fish, corals and many other things in these types of tanks.
sunlight
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.
no there are no tadpoles in the coral reef they can not live in salt water
soft corals live deeper water than hard corals because soft corals do not create a hard outer skeleton as the hard corals do.
I think you need water in your system and salt in your system but no salt water..................I think
yes they do
You need a salt water chlorinator. A salt water chlorinator is an electronic devise that converts the salt in the water from the pool into chlorine gas that is then absorbed into the water.
Hermit crabs do need both types of water but they need both water because they need to clean themselves and they just drink salt water.
whats good about salt water is that fish that live in the ocean need salt water to survive
