	I would not be surprised if it is indeed NOT a essential 
nutrient, but it is found in a couple of the supplements that I give in 
my tank. Maybe "essential nutrients," however, is not the most 
appropriate name for any mineral supplement, whether it be Seachem, Kent, 
Tetra, Dupla, etc... I will continue to search for me source and let you 
know what I find.
