You need reef mud.
The Mud / Eco method
If one were to take the basic concepts of all the methods above you would have the Mud System.
Envision removing all the bio-media from the sump below, place a layer of 'mud' across its bottom, illuminate this chamber with light and grow various algaes within it, you would have the Mud System. Granted that is the simplified version, so let me explain.
The layer of 'mud' becomes a low oxygen enviroment allowing various anoxic bacteria's to perform de-nitrification. The algaes harbor many small creatures who help break down the debris, and in combination with the debris this enviroment creates a fertile area for the plants to grow. The plants, via photosythesis, consume a large percentage of the nirtogen rich debris. The illumination, which is the opposite time frame of the main tank, provide the energy for the plants, as well as, minimize the pH and carbon dioxide fluctuations within the aquarium.
Within the tank, at the bottom, is a layer of sand. Placed upon the sand bottom is the live rock. The live rock forms the foundation that the living corals are placed upon.
This was gotten from here....
We, as a people, know so much more about outer space than we do about our own oceans. This lack of knowledge can very well spell the dangers that lay in wait for us.
The oceans surely would swallow us before a rock comes down to smite the planet of it's life.
