I live in Armenia and I am only person to import corals,But I am new to these and need some help.
Some of my soft corals are loosing tissue.it looks like open wound on my blue xenia,sarcophiton is loosing tissue from the bottom.
What can I do to save them?

put some activated carbon in the tank, im sure the leather is putting out tons of chemicals harming all the other corals.
