Hello there I bought a yellow purplish coral three days ago, I have VHO pumping out 490 watts. It seems that the coral is de attaching itself. It also seems that the leather is deteriorating. Because when I moved it to a higher level of light it was releasing small yellow particles. Does this mean that it’s dying? should I just leave it alone ? and if I do leave it alone and it dies, well it effect the rest of my tank parameters?
