I got some feather caulerpa from waldo a time back, it only had two feathers. i placed this caulerpa in my sump with the grape caulerpa and cheato. my feather c. made 4 new feathers in the sump, i took it out my sump 3 days ago and placed it in my DT, it made 10 new feathers in 3 days! warr told me one should only house one type of macro algae, i would really like to know if feather caulerpa would be bad in my DT? I got a liking in macro algae, i have different types growing in DT why should i get rid of my grape( in sump with cheato) and feather caulerpa?
