Caulerpas and photoperiod

[arrow crab]

I've read certain macroalgaes such as caulerpas "going sexual" is not as bad as it's made out to be, but it can still be a pain if it's easily avoided.

I also remember reading somewhere that if you give it more light hours than dark hours in a 24 hour period, it won't go sexual at all. It only does this if you are at 12 on,12 off. Is this true?

I have the regular looking leaf type and give it 18 to 24 hours, been fine for a couple years. I'm on top of trimming though

Have the long ferny type of caulerpa. 14 on to 10 hours off. So far so good.

Thanks! I'm going to grow out a crap ton of different kinds. I like the feather caulerpas ...
