I have a bit of prolifera and it seems to be doing well, but I was wondering if I need to worry about it going sexual. I do not keep the lights on in my refugium 24/7. Does go sexual as often as grape caulerpa? How often do I need to trim it. Thank you.
Any Caulerpa, and probably any macroalga, can go sexual. I'm not sure if its as prone as C. peltata (grape caulerpa) but this group of plants typically does it when it cant get enough nutrients for an extended amount of time.
I'd trim once a week or every two weeks, and halve the amount of plants you have, particularly if you're using for export purposes. Keeping the lights on 24/7 may be good insurance, I've never done it though.
