This is a csb that has been completely green and grayed out for the past 6 months. It's very faint but in the right hand corner it's regaining its color, that fiery orange is starting to come back. This was after only 2 weeks of feeding it Amino soaked salmon, and setting it up with an AI Prime above it at 30%. I have been eagerly searching for information on how to make its recovery possible. Others told me from other groups explicitly not to feed salmon, because of Mercury ect. Just be mindful "treatment" plans you get from others. Ask questions like have you experienced this problem before, how long has it been since you treated something like this, what was your success rate? Is there a more holistic approach? I did everything on the strength of other groups from Cipro dips, to treating the whole tank with different medications. Marine life veterinarians, Nationwide emails sent out to the vet Cor organization (wife works there) and then some. After banging my head against the wall because I hate when I can't solve a problem, I Googled superfoods. Didn't want to feed avocado so salmon it is. Praying for a full recovery. We are on the right path.
