My mushrooms are melting, Please help.

[m_kun3]

I've got two of yuma mushroom since last saturday a few days later they looked fine but now they seem to be melt with no reasons. i put them at the bottom of the tank (not too much light). My tank is 72*30*30 inches using 400w*2.

Anyone can solve this problem please? Anyone can please point me why the mushroom coral melting?

What is a cause of this heppening?

What is your temperature and salinity level? Most reefers do not see a point in acclimatizing corals. I feel acclimatization is as important in corals as compared to fish, corals are invertebrates and they would be more sensitive to fishes in sudden changes in parameters.

could be your light is too strong , place yumas in a shaded area of your tank ,

but if they are melted far too badly , you might not be able to safe them.
