Half of my acro is bleaching??

[Silentreefer]

I have a lady in pink acro that originally bleached a while ago and has slowly been coming back, but now half is bleached (again) and half is a very dull pink/brown color. Also the bleached side is facing away from the light. Everything else is fine, about 20 other acro frags a couple lps and softies I had two other acros that bleached that are still coloring up like normal.

Last I checked my parameters are
8.0 dkh hannah
456 calcium hannah 440 redsea
1420 mag red sea
Dont test for phosphates or nitrates

Just found it weird and wondering what might cause that. I'd post pics but 1 i dont know how and 2 you cant notice the difference in the pictures anyway.

Light is too strong , or your NO3 and PO4 too low .
Thats my opinion.

I would agree with you except that the bleached side of the frag is facing away from the light in a spot with 140 par, the bleached side is and inch away from the glass do you think the glass would reflect enough light to do that? Low nutrients could be possible but everything else is colored nicely not pale, and I have to clean the algae off the glass atleast once a week. I should test for it maybe today if I have time.
