Used to be (under the Jack Kent and Chris Brightwell years) that they would call out impurities as ingredients on the label. Kent marketing was a lot more loosey goosey with the labels before it became a CG&P company. Now we follow the rules and use the AAPFCO fertilizer standards (although it is not a fertilizer) as a guideline.
As for why it works on Bryopsis where others won't, I can't tell you as I don't really have enough data to form a conclusion.
