I was asking about brands because it seems many are not pure amino products, they seem to contain many other things. Some have vitamins and trace metals, others have carbohydrates, some say nothing? Someone mentioned cyano outbreak? Is that from the aminos or the other additives like carbohydrates? I agree from what I have read that aspartic may be the one used most in calcification, and glutamic seems to produce polyp extension, as well as getting incorporated into the coral. If we see good polyp extension and we get better coloration and growth, then when do we reach a point when we added to much? What would we be looking for if we overdose? What type of bad should we look for? Higher nitrates? Bacterial growth maybe including cyano?
