Bleaching Stylophora

[Sniperhank]

Ok. I have had my pink Stylophora for several months now. I have been working on lowering the intensity of my lighting and noticed that the side of my Stylophora that was facing the lights is bleaching. The odd thing is is that the underside is no longer pink, it is more magenta. Lighting has gone down 25% over about a month and a half period. Any ideas?

Oh, I guess I should add that I moved it into the sandbed when I noticed the bleaching.

Can I ask what type lighting do you have? What is your calcium reading at?

 

[Sniperhank]

I'm running 2 Ecotech Radions. Working on the calcium reading as we speak.

Also if you look at the one at the top it has some white spots on it too.

I see that...I'm just concerned that half of the thing is white where the other has darkened to magenta. The stupid API calcium test went at 25 drops and still didn't turn...I think it went bad. It should be at 450 calcium from my weekly water changes.
