Caulerpa for my sump

[fishfreak2009]

Alright, so now I'm scared. I've been reading about Caulerpa going sexual for the past few hours, and it seems that grape caulerpa does this most commonly. I have been growing grape caulerpa in my simp for the past 2 years with no problems, as well as caulerpa prolifera in the main tank for the same amount of time. I've never had any problems and I regularly add the grape to the main tank because it's always gone within 24 hours (the bicolor angelfish loves it). So here's the question. I'm upgrading from a 20 gallon sump to a 55 gallon refugium/sump combo. The lighting is going to be stronger and there will be other algae present (Chaeto and gracilaria). Should I just trade the caulerpa in? Will it go sexual? Or, should I just keep it in the sump only, and keep an eye on it? I am going to add a sea urchin and a few tangs to the display, so should I just let them eat it all? Tank is 187 gallons.

I've never been a fan of Caulerpa. There are far better options available in terms of a stable population. There are also plenty of others that don't excrete various organic compounds nearly to the extent that Caulerpa species do. Stick with Chaetomorpha or something like Ulva or Gracilaria.

On MFK, they told me that I shouldn't worry about it, because I was planning on adding a school of 5 yellow tangs to the tank anyways and it would provide them with a free meal :naughty: Also I have a bicolor angelfish that loves the stuff, and I was planning on adding a long spined urchin to the tank (lots of corraline and my old one destroyed all caulerpa it happened to crawl over. If it's really going to pollute my tank I may just grow it in a 10 gallon as a steady food source for all the animals.
