Cant remember, I personally make the water look like a tea color type water with the dip. and only leave them there for 5mins max.
But the lugols solution it self has a dip instruction in the back, IMO that too small a concentration especially with all the pest that CAN inhabit or hitchhike on a zoo colony. I use Tropical Marine Coral Cure, I believe its currently the best coral dip out there...
