Brown 'green' star polyp
No matter what I do, I can't get my GSP to be GREEN down to the root. Only the tips are green, and the rest are brown.
8-9dkh
470PPM Ca
5 nitrates
800watts light over 140G
lots of flow
All of my corals, mostly LPS with some SPS are really healthy with great polyp extension.
Even the GSP has full polyp extension, and when I bought it, it was totally green.
HELP!
