Do bubbles in the tank have an effect on leathers? I heard something I think.
What your describing sounds more like sloughing
. Leather corals will go into a dormant stage which allows them to shed and rid their outer layer of impurities. It can also be a reaction to a stressor such as being in a new tank, exsessive water flow, coral chemical warfare or other irritant. Minor bubbles might irritate the coral somewhat but unless they become trapped for long periods of time will not normally cause necrosis. Also watch for detritus accumulation on the top of the crown. It can lead to necrosis if left too long.
As long as the coral does not show signs of the flesh crumbling or turning dark colors, it should be okay. Take a small eye dropper or the like and gentley force water over the various parts of the leather. If pieces start flying away, it's necrosing. If you just get a bit of outer slime peeling away or nothing, it's sloughing
