I added some caulerpa, chaeto and mangroves to my refugium a few months ago. Unfortunately thate ld to dinos (red strings that attached to my soft corals: corky, Kenya tree and gorgonian).
After researching, I assumed this was due to zeroing of nitrates (my nitrates always read at our near zero on API tests). So I cut the refugium light hours from 16 to 8, and removed the skimmer cup. That eventually helped clear the dinos, but I think the damage was done as the corky finger is not looking good.
Can this recover? Or should I cut off the bad arms? The top part above the bad part still has open polyps though.
All my other soft corals, mushrooms and lps are all looking great.
Thanks,
Scott
