Amount of light for caulerpa

[Crash64]

I am looking to grow lots of caulerpa in my tank, I have always loved the way it looks in an tank, but never had any success. I am wondering what the lighting requirements are, in a per gallon ratio. And what else can be done to get it to grow. (i.e. dose adding iron really help). Also, if it goes asexual and spores will it kill anything?


Thanks

Caulerpa will grow under pretty much any aquarium lighting, but the rate at which it grows is related to how much light you have. The more light, the faster it will grow. Dosing iron will help it grow if iron is the limiting nutrient in the system. But you probably don't know if this is the case, so I wouldn't dose it. If it goes asexual I don't think the spores will kill anything. The only way it will kill something is if it overgrows it. FWIW, I have caulerpa growing in a tank with 500 watts of halides, a refugium with a 9 watt PC light, and my brother has it growing in a tank using a desk lamp for lighting. So I wouldnt worry too much about light requirements. HTH

Well really I am more concerned with how much light is needed to make it go a sexual.

I had it go sexual in my 75 gallon under 400 watts of PC.

It didn't hurt anything though. The worst part was that it managed to grab hold on some areas of the back glass that I couldn't reach. A couple of months later it all died and I haven't had it return though.

I just tried some in my 10 gallon under 96 watts of PC and it isn't growing very well. After about a week, most of it has died off.

Does anyone know how I can get it to stick? Maybe I should try a little bit of iron.

I have searched the forums looking for more information on this aswell as the internet. And I can't seam to find anything that has in-depth info on this. Dose anyone know of any sources of information on caulerpa and the amount of light it requires. Thanks
