I got a two small frags (5 heads) from someone and there's what appears to be GHA growing out of them; one is a beautiful Paly that was open for the first four or five days and for the past two weeks it hasn't fully opened. It's not closed up tight, but obviously not happy. I have some seachem iodine coral dip, will a bath in this stuff help remove any nuisances growing on the frags? I have 7-8 other species of palys/zoas doing great, just hate to lose such a nice frag if I can prevent it, as well as not wanting to see this GHA spread further in my system. If the seachem dip won't take care of it is there anything else I can do to help it along? Thanks, Pat
