Still had evidence of the dusty stuff in the basin and a few white tendrils swinging from the polyp holes. I gingerly picked at one and it turns out that it has substance that I was able to pull out. Tastes awful.

This colony is position as seen in the picture, thus the lights are striking it broadside. The back is not bleaching, but it seems as if the greeny part has pulled back a bit, or maybe the greeny part is moving forward to compensate for the added light where none was previously.

I also shifted the direction of the return nozzel that was blasting it from behind. My hairy musrhooms always excude a white tendril like material when I lift them out of the water or overly molest them. I'm wondering if perhaps the added water jet was stressing the coral out. I'll learn more tonight when I get home. This morning there wasn't much of a change positive or negative.

May be that I have to realign the entire colony to receive a more direct path of light.
