For a SPS reefer this could very likely be the worst nightmare situation. I have an acro heavy tank and have been red bug free for over three years! Last night while admiring my tank I noticed that some of my acros looked "off". As I examined closer I noticed that I have been infected with red bugs. Where they came from I don't know nor at this point do I really care. I have done hours of research on a cure that is "reef safe" and have been let down. The most effective treatment seems to be the meds from a vet for de-worming which unfortunately is not going to work for my situation as I have too many "permanent" invert residences in my tank. I can though remove all the colonies of acro in my tank as none of them have been allowed to encrust on any base rock for this specific reason. Someone please help me I am in frantic mode!
