Hi Friends - I've had this Millepora for almost 30 days. It has been coloring up, some base growth, and otherwise looking good. Today, I notice this white stringy material at the base. It appears to be on the flesh as well as the frag plug. The coral does not appear to be bothered about this substance, and the substance flows in the current. I haven't seen anything like this in my tanks before so hoping someone has an idea. I have not attempted to blow this off or disturb the substance. Thanks in advance.
