what do you think about feather caulerpa?

[JeffersonReef]

I have some feather caulerpa growing out in my fuge. It just EXPLODED while I was on vacation. I switched to the melev fuge bulb, and started dosing iron... and BOOYAH! Chaeto stopped dying. Only problem (?) is that there was a small strand of caulerpa that has grown like a weed! In a week, had increased ten fold! No exaggeration. It is starting to attach to the rubble and sand in my fuge. Should I get rid of it or keep it? I really wanted to just grow chaeto for nutrient export.... will it harm the growth of my chaeto? What do you think?

i had both when i ran a fuge. the chaeto tended to outgrow and overshadow the caulerpa so it never got out of control.
