I have been reading on here that people will do a fresh water dip to remove unwanted hitch hikers and thing of that sort. \n \nI was wondering if some one could explain the procedure. \n \nDo you take the item and do a quick dip in the fresh water? Then pull it out? \n \nDo you heat the water first to near tank temps?\n \nWill this be an effective way off ridding my self of pested Mantis Shrimp?
