Hi guys. I hope someone can help. I recently acquired some hairy mushroom frags. After about a month of having them, I noticed some flatworms on them. I'm 99% sure they are flatworms, and after close inspection am sure this is the only coral affected. I will be able to remove the frags for treatment. Is a freshwater dip the best thing to do? If so, how do I do it? Thanks in advance, Joel
