Purigen shouldn't? Purigen removes tannins and uracil (and maybe other things but seachem doesn't specify).

As for carbon, it wouldn't matter. I think carbon removes it but it wouldn't strip the tank of them before the corals can grab some.

I don't think there will be a lot of these bound by either one, but the most hydrophobic amino acids (e.g., phenylalanine) may be somewhat bound to GAC, and certain amino acid that carry a high charge (e.g., aspartic acid) may be bound to Purigen.
