Hi over there in Waynesboro!!!!!!! Which LFS do you use ??
I see you where looking for any and all advice. Is your lighting new for one question, A sudden increase in light will cause it sometimes. Two, like others have said, look at your phosphates levels, higher phosphates can lead to outbreaks.
Number three, (the one that worked for me) try cutting you lighting WAY back for a week or so. It will not hurt any corals you do have adversely. If prams are all in line cut the lighting way for a week or so.. Even doing this on a regular schedule is not a bad idea. ( like a two or three day storm reducing sun light on occasion in
nature.
I had one spot of the stuff that slipped by me on a frag that I pulled and fought forever. About 2 months ago I broke a leg on my hood. Sooooooo I
keep my lights off or only on with the actinic (blues ones) for short periods for over a week to keep the heat to a minimum till the new one came.
Guess what no more green crap!!!! The much reduced lighting was the trick that worked for me. !!!. Now if I ever see a trace of it show up anywhere , back down goes the light for a few days and it magically is gone!!.
