Before and after biopellet photos. How do I bring my montipora back to life?

Well, they worked for me, but in my case I had nitrates as high at 100 ppm. Down to less than 20 now. Really cleaned up my tank, too. No algae or cyano. I just have LPS and softies, and they all seemed to like it.

I have heard of corals getting bleached after bio pellets. Perhaps they need a trace amount of nitrates/phosphates, and the bio pellets depleted them too much.

Also, more recently, some people have reported coral bleaching and dying after use of Kent carbon.
