experimental treatment:
CTRL = no nutrient additions;
+Si = addition of volume of 0.1M sodium metasilicate (Na2SiO3) solution to increase ambient dissolved silicon by 20uM;
+Fe = addition of volume of 0.01mM ferric chloride (FeCl3) for a total concentration of 1nM;
+Si+Fe = addition of both Si + Fe;
+N = addition of volume of 0.1M sodium nitrate (NaNO3) solution to 20uM;
+Si+N = addition of both Si + N.
