How dangerous is it to use Caulerpa in my Refugium , what happens if everything goes sexual ?
I am lighting it for 22hours a day - have heard mixed opinions on the lighting schedules to prevent it .
 
If it goes sexual it will release spores and you will have calupra all over your tank.
 
When i started the hobby i had a large refugium with plenty of caulerpa and it went sexual three times, with two different species. The water went murky for a bit, and thats about it. There was no mass death or anything like the hype on the internet suggested.
What seemed to help (and i havent had it go sexual in ages) is to keep it trimmed. Rather have many short pieces instead of a few long strands.

Thanks 459b , reassuring , I find it more attractive than chaeto , as I can feed it to my fish. Did all of it go sexual at once , and how did you restart it ?
 
Not all of it did it at once, so there was enough to regrow. Since being diligent on trimming i havent had any issues.
 
Maybe should add that ive had fern, leaf, strap, grape, and serrated. Only the leaf and fern have gone sexual. Currently have leaf and serrated. Would like to get strap again, that has been the best in my opinion.
 
long ago I had grape type that went sexual twice within 4 months. A small strand survived each time that regrew. Heavy trimming helped in preventing it from doing the same again.

Luckily that was in a holding system, both times it crashed was just as I moved fish out of there. Seems as soon as the nutrients drop it triggers the action.
