Hi, recently I realized my duncan had been receding, but didn’t think too much of it because I just got a new powerhead. Then about 30 minutes ago, I realized it was spewing a dark brown/black mucus and realized a larger lesion/infection on it. I just finished dipping it in Seachem coral dip for about 30 minutes using the dosing instructions on the bottle. How often should I be dosing it now. I should also note that right now I do not have/ cannot get a quarantine tank for it, and am keeping it in my main display tank (25g Waterbox peninsula).
