CFM can be used to reduce the temperature of the seawater around the coral and purify the water. The wind drives the bump which sends the air in to the CFM in bottom of sea. With the air flowing, it can bring the seawater into the Honeycomb AC then it will absorb impurities and generate micro bubbles. The bubbles will flow up and carry the thermal energy which in the bottom of sea. Finally, the wind that from the wind turbine will blow those bubbles off, in order to reduce the temperature of seawater. The part of CFM is calcareous ooze, which benefits the growth of the coral polyps and algae.
