Ocean, same here. I have two rocks that were awesome. They haven't been out in a week or so. Water quality good, still in flow and same light that they had been receiving for months and all the sudden....Kaput! Don't know what is happening! The only thing that I have changed is that I started using RODI water instead of tap. All other corals are doing excellent.

My gsp rocks are doing the same. but they do it off and on...one day they will be open and the next they will stay closed....

I just read this today, but all I did was put some iodine in my tank , a little extra . Then about an hour later I use a turkey baster and pump some of the tank water right at them. I notice a little algae on them. I blew all of it off and now they are blooming just fine.

I was having the very same issue with my green stars too. The culprit was my actinic light. It looked ok, but was dimmer than normal. It was over a year old, so I just replaced it this week. Two days later, everything is looking better than ever and they already seem to be spreading a bit!
