What’s up with this guy?

[Yumme]

Had my green finger coral for ~6-8 months. Has been retracted for the past 2-3 months with no growth.

Params fine apart from phos 0.17. Dosing zlements one4all and nopox weekly after 10% WC.

Indirectly in line of flow (located opposite corner to power head). Lights are on 90% WVB for 5 hours of the day, blue is on 90% 11 hours.

Advice appreciated.

So mine has this when I moved it into lesser flow. Moved into a little moderate flow and it liked things more.

I agree that more flow could help.

 

[Mr. Mojo Rising]

+4 for more flow

I see at least, one Aptasia on the left at the foot, maybe more, they will bug the crap out of the leather.
Remove.
