I too had the same problem. I started with a little bit of caulerpa in my 10Gal refugium. It was growing really well. About 1 month ago I had a whole tank full. Now I think I have one strand.
I thought may I ran out of nutrients (which is probably unlikely).
Should I try putting more into the tank or is this a bad idea?
What happens to the nutrient level of the tank when it all dies so quickly?
