Hi all, my rasta zoas are not opening fully. I noticed this with my vamps in drag zoas so i used a turkey baster to blow it and it closed but 5 mintues later it opened fully. I figured there must have been crap or gunk on it. I did this to my rastas but they opened just a bit more but not fully. I think there is algae or something growing in the middle of the frag so how do i get rid of this? I do not have any coral dip at the moment.
