Zoas shrinking/turning brown/ disappearing

[60gallonrimlessYA]

I have questions that would like to discus about. I have some zoas in my tank that are beautiful and have grown then I have zoas that close up and have brown on them I have a Redsea reefer 250 with a Radion gen5 Xr blue that’s on the arm with 2 Mp40 a that are on constant mode at like 3 light on the back wall of tank What is the best settings I should use to get all my zoas to stay alive

Light settings?
Mp40 settings?
How long should lights be on ?
What intensity should the light be on ?
Water flow ?

I’ll get pictures when the lights come on I’m working on bringing down the nitrates and phosphate with water changes but it’s crazy how some do amazing and others wither away

I have the reefer XL300 with 2 XR15 lights running 100% intensity on AB plus schedule for 10hrs. My MP40s run at 28% intensity on reef crest. I have a bazillion zoas.
