Also added a kessil 360we between my 2 150 watt metal halides about a month ago and have been slowly cranking it up.

I know it looks green but the whole base looked the same a couple days ago.

Maybe I'm over reacting?

I personally dont see anything. I would turn off lights, and shine a light on it, or take a photo in all whites

Mine did this, then the colony nuked (I did cut it and saved a ton). Not saying its the same thing but I'm sort of still battling it, I think I have a bacterial issue going on.

In this pic you can see the upset polyps on the base, the ring around those upset polyps was once vivids and colorful. It slowly changed to brown/green algae color. Didn't look like a typical stn (white) which is why I waited a bit before cutting. I wish I cut it sooner.

it's now growing out again in the frag tank, I'll move it back to the display soon, but it re-grew the base on a 3x3" plate (you can see the plate in the pic and the base growth).

Thanks for your reply that's exactly what I needed to hear. Not a typical STN event. I'm gonna frag it today.
