Wow, Joe, this is interesting..... I read somewhere that Chaeto was the algae you could light 24/7, and caulerpa needed a diurnal cycle or else it would go sexual......maybe a different sp. of Caulerpa??
I have a big ball of chaeto in my sump that I've had lit constantly for the past few months, and it's only getting bigger. My pods love it, too. I'd love to hear why you think Caulerpa is better. I can find it down here in Fl. from time to time, so I have the option of changing out if needed.
Caulerpa is faster growing then Cheato does better in refugiums that do not have a high turnover rate that Cheato prefers (tumbling) it will root (not really roots) to your sand or mud substrate (helping aerate it). You can feed it to your tangs they seem to love it. Easier to harvest.
24/7 lighting Is not the reason caulerpa will go sexual.Actually I believe I have read that there is some evidence that keeping caulerpa illuminated 24/7 will impede it going sexual. Of course keeping It illuminated 24/7 assures that it is kept in your refug
