Re: chromium as a nutrient
> Chromium is not known to be an essential element as far as I know for any
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.
