Thanks for the responses! Yeah a solid week, I've done a 2-3 day lights out before without ill effect, but never a week. I've read some even think it is good for the tank to have a period of darkness but in this case it had to be a week. I wasn't sure if the green polyps could sting or harm the hammer, I guess all corals have a defense either physical or chemical right? Oh about breaking off the branch, won't harm anything will it, I mean just calcium right? No feelings or harm to the coral? Anything to help a coral such as mine to recover when something like this happens?
