I am new to this list and apologize in advance for this intrusion of an 
aquarium question, but I need some expertise in coral physiology and 
biochemistry. Would "calcium ions, hydrogencarbonate, and trace minerals", 
when used as aquarium additives, be considered nutrientsfor either the coral 
or their symbiotic algae? Are the minerals only extracted/precipitated for 
use by the corals or is the a biochemical metabolic process involved that 
could cause these additives to be considered nutrients? I am trying to 
determine the status of commercially available additives in order to fairly 
apply reqirements under feed/food statutes regulating pet products in the 
USA. Thank you for any assistance and if this forum is inappropriate, a 
little help redirecting my inquirry would be appreciated,
