capnella opens but stays small. All corals doing well stony and sixties alike. Its been 8 weeks and capnella struggles. Is it too much light or is sps irritating it?. Carbon did nothing. And neither did flow changes.

Sps won't harm it but your increase in lighting may have shocked it. Where is it in the tank and how much light is it getting?

Its in the furthest shady corner possible. I appreciate your quick response. Maybe it needs to go back to lfs
