It was brown and slimey. Normally it was vibrant green.

Hmm, sounds more like a disease than anything, though I've never heard of anything like this.

Wow, thats strange man.......guess I can't buy any from you now..lol

I've never heard of anything like this either. There are only a couple of strands of it left that appear to be clinging to life. Hopefully they will re-grow the patch. Incidently, there was a little bit of chaeto in the fuge as well that didn''t seam to be affected at all.

Hmm, that's interesting, so it was only the Caulerpa... just a single species? If you have more than one species and only one was affected, I'd say most definitely a disease of some kind. I'm leaning that way anyhow, if all other things are equal and because your Chaeto is fine... try checking out the forums at http://www.marineplantedtanks.com, they may have some insight for you there.

This happened to me as well. It never happens to cheato and that is why some people never keep caulerpa

I found this :

Caulerpa spread almost entirely by asexual growth from spores and by fragmentation. A spore producing Caulerpa can often times release such large numbers of spores that it turns the aquarium water a milkly-green color. If this occurs the spores will settle out, be removed by filtration, be eaten or die off in a short period of time. The water becomes clear again, but the spore producing alga can leave behind a white soft tissued husk that should be removed.

HI Guys,
I had a book by Anthony Calfo, who is I guess some kind of reef Guru

, and in there he warns about the nutrient levels getting too low and the macro algae going A sexual, at that point it realeases all of the nutrients that it has pulled from the water back into the tank at once. Which is not good considering many of us have used macroalgae for nutrient export. test your water for nitrates and phosphates and maybe do a nice water change to be sure. Good luck.

Yeah, that's why I asked what it looked like when he removed it... I assumed it had 'gone sexual' but wanted to be sure because if it had gone sexual, he would have been removing white stuff instead of brown stuff.
