If you have caulerpa in your main tank or refugium, please let me know how you like it and if you have ever had a problem with it going sexual. I just finished building my new sump and it now has a proper refugium area so I plan on getting many species of macroalgaes. Some people seem to love caulerpa and some hate it, but I like the look and hear it is good for nutrient export so I would like to have some.
