These frags at the top of my rock have high flow, 350-400 par and water is good. Only Alk is a little Low at 7.2 and PH is at 7.6. Everything seems to be ok except that the middle one is bleached out except light blue tips. What could be the problem?
Some pics of other coral show the water is fine
Not all frag will survive. So give it time and if nothing more is dying then u are ok. But for anyone to help you we need more details how old is the tank? Volume ? Start with dry rock or live rock? Other parameters etc....
