Macro algea turning white

The macro algae I have in my DT 35 gallon is turning white. I was thinking for awhile that it was new growth, now almost all of it is white and really soft. Does anyone know why this is? Tomorrow I am going to run test to see. I have soft corals and all the color is fine. Keep my white LEDs on 7 hrs a day, run them at about 75%. Thanks for your help!

It sort of looks like that. When I started my tank a friend gave me a handful to start. This is what it looked like when it was green. I will get some pics in the morning when of it being white. It is really soft to the touch too, almost desinagrating (spelling sucks).

Remove it that's grape culepra and when it turns white like that it releases nitrates back into your water

While it has been white? It turned really fast, maybe a week. But it was in there for about 4 months being green. Why did it turn white?

I am not sure for your particular macro.. But i know many type of macro "melts" and will completely disintegrate into the system and then a period of time later it will reappear growing on your rock in all sorts of places that are suitable for it to grow. That may be what is happening.. It usually starts to happen within a few days of putting it in the tank though.
