Here is the information on the Lugol's dip written by Eric Borneman on RC in this thread.

b) Lugol’s solution: We used two high dose Lugol’s dips as a method of dipping to kill copepods. Within about 30 seconds, most copepods had bailed off the corals, and fallen to the bottom of the treatment vessel, rapidly dying and turning black. Several corals maintained attached to the coral but were dead. The dose level was 5m/L and up to ten minutes was tolerated by even highly colonized corals, although the effect on the coral was seriously stressful, resulting in partial bleaching, abnormally increased mucus production, and in a few cases, death. The majority of corals survived and recovered within a week and without any copepods present. The duration of treatment varied from 3-10 minutes, and examination under a dissecting scope was done every minute to assess the status of the parasites. At 10ml/L, copepods died generally within 30 seconds, with some lasting up to 2 minutes. The effects on the corals were more pronounced and resulted in significant mortality, especially at durations from 2-5 minutes. This may be a good “dip” method for minimally colonized corals that can tolerate the high dosage of Lugol’s solution.
