I think its Grape Caulapra? What ever it is it grows very quick. It has runners that dig into the sand and rocks. Its only in my CPR refug. I have tryed to keep Cheato alive but it always dies no matter what light I keep it under. I'm using a Jalli 24watt light that is used for the CPR refug. And this algae is growing crazy. I want to keep it if its good for export of nutrients:rolleyes: Its the only algae in my refug.Also how can I keep it from going sexual? I keep my lights on for 15-16hrs a day
