Do you add some iron supplement? If not you might want to consider using one such as Kent Marine Iron & Manganese.
If you have corals it will also help with green color! Don over doss a good indicator of overdosing is when your acro, yellow Blue etc are getting greenish halo.

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.

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.

Danny: if you ever come down here, I have some feather caulerpa I could give you, if yours dies off.
Also have lots of cheato

I do dose Iron/Manganese from Kent. It's good to know about the green halo in acros. I haven't noticed anything like that in my acros, so I must not be over doing it.

Hillegom - I appreciate the offer, thanks.
