I need to do an iodine dip for one of my colonies of zoas, the spaghetti worms have gotten so numerous on that particular rock that they seem to stay closed all of the time. I have on hand Kent Marine Concentrated Iodine ([url=http://www.marinedepot.com/md_viewItem.asp?idproduct=KM3173]Kent Marine Super Iodine 8 oz. - Marine Depot - Marine and Reef Aquarium Super Store[/url]) but am unsure of the dosage and how long to keep the colony submerged. Any help would be appreciated. Thanks.
