Well I would confirm levels, MAG, ALK, CAL, PH range etc..
It this the only 1 showing polyp extension issues? Poor polyp extension could be multiple possibility. Water quality/params off, pests, flow, lights. Light is probably the issue in this circumstance but check the others
I know I have mine a bit to high, wish it was mid level.
I will tell you from my experience I put mine dead center top. Was doing great with deeper red and green. I was doing some light level testing(really should get someone to test my par) on my tank(increasing blues and white over period weeks/months LED). Anyways the increase of 30% in whites in the end eventually dulled the green to almost a cream and even my joe base was white vs green. Also noticed reduced polyp extension. Lets just say I am back where I started at 35% white 100% blue overall and that is where it will peak each day. Colors are making a slow comeback. Notice I said SLOW, so the key is leave it alone for a couple months and see how it recovers.
I would say mid level placement with good flow would be what I shoot for.
Hopefully others can chime in with their first hand experiences.
PS this is from ORA page
Description:The ORA Red Planet is one of our most popular corals. It is a tabling Acropora with red and pink corallites and a metallic green base. Polyp coloration on this coral is a deep red and the new growth is light pink to white. Under intense lighting the coral may lose the attractive green coloration, it will return if the coral is moved to a lower light area.
Placement: All Levels
Lighting: Medium – High
Flow: Moderate – Strong
