Do you have Halimeda in your setup?

I'm opening a poll on the usage of Halimeda. I'm very curious about it's interaction with other inhabitants. I have an anemone that started to decline suddenly and the only thing that changed (that I'm aware of) was the addition of some halimeda which it came into direct contact with.

I hope I covered all the possible answers. Please post comments as well.
 
I have had it in my refugium, but it sucks up calcium VERY fast.

Recently I found out that it also can 'go sexual' like Caulerpa sp. so that's another strike against it.
 
Can be pretty when well maintained but not enough to justify the calcium uptake. My tank is SPS-oriented so that's an issue for me.
 
None really apply to me...

I've had it in my display and in my refuguim at various points.

It never caused any problems, but it was totally obliterated in my display by my Tang's, and it was out-competed in my refugia by my Caulerpa...
 
I have had it in my disply and sump/fuge for over a year and never had any issues and worth every bit of cal. it used for the nutrient extract.
