i am in need of some help with my corals. I have a zoa colony that had bubble algae i thought i got most of it out and its been about a month and now i seen a huge outbreak of it as it has grown back on the same zoa's and my other zoa's have it as well now ? i am switching to a bigger tank (after it cycles ) and i realy dont wanna put them in the new tank till there free of this bloom i have. I know people say you can get emerald crabs to eat it or you could cut it off which i done once and made a big mess with it . The colony had doubled in size since and has taken over a descent size rock. Im open to ideas or if someone who has had this problem before and cured it would you be willing to show me what to do ?
