What's happening to my SPS?

[tdyrkacz]

As you can see one of the branches is getting quite white. I just pushed a crab off of it he has been camping out on this branch for at least a few days. Is he doing the damage? It was a blue legged hermit crab. I've had this coral for about 5 months and it's been encrusting and growing nicely. I've seen hermit crabs camping out on it before, but this is the first time it looks like this.

This appears to be a very bleached digi. What are your parameters?

 

[hybridazn]

It doesn't appear to be happy at all. Def post up parameters, lighting, flow, placement and so on.

Calcium 435, alk 9.2

All bad stuff non detectable. I have 2 MP40s and 3 Acan Leds, which are not running at 100%. Here is a pic of the placement.

You can see it right behind the hammer

I'd lower it, digi's aren't a high light coral. I bet it was light shocked.

Digis are pretty resilient. I would try moving it lower and see if that helps. What color was it to begin with? Red/Orange?

It's pretty well encrusted onto the rock it's sitting on. Not easy to move..... I did add a led fixture about a month ago. Should I lower the intensity for a while?

Yes I would lower the intensity to start.

Maybe the hammer is stinging it after lights are off . How far apart is it between the hammer and digi

Less light and more nutrients will probably help.

Hard to tell from the angle i showed but they are about 12" apart. I will try lowering the lights.
