Not much of a 'fix-in-a-bottle' guy but I've noticed lately that some of the colors in the tank are looking a bit...off. All parameters are within acceptable limits and there have been no changes in lighting or husbandry. A well known and highly respected aquarist recommended that I begin dosing a certain amino acid. Never used them before so I thought I'd ask: If I dose according to directions, can I do any damage to the inhabitants (SPS)?
