I have several acropora that have completely bleached and are totally white, but the polyps are extended and seem to be doing fine. There is even a little pink colour to the corals themselves. I'm assuming that most if not all of the zooxanthellae are gone. Is there anyway to provide new zooxanthellae for reincorporation into the corals?
