RAINBOW ZOA POLYUPS CLOSED

[RoadGlideRon]

hi everyone.. looking for help,

i have a tideline 62g. tank has cycled and is now about 10 weeks old. currently i have 2 clowns 6 nassirus (sp) snails, one mean green zoa, one rainbow zoa, and one gsp. orbit2 set at 48% during day, 24% night, AI 48" Blade 2 hr ramp to 45% on rb and b.. with zero w. salinity is at 1.025 and nitrate-nitrite-AM are at zero.

what's up: so all 3 corals were doing fine along with the clowns and cleanup crew. i raised the Blade to 65% rb and b and set w to 9% (2 days). Then i cleaned my Orbit2 , but installed it upside down which placed the direct flow onto the rainbow zoa.. i reset the Blade back to origional and flipped the orbit2..that was about 10 days ago. Currently gsp and mean green zoa are fine.. but my rainbow zoa has several polyp'sthat remain closed. i've included image, and it's hard to see due to the blue lighting..

thank you in advance for your help,
ron-

I would raise your nitrates up from zero, they should never bottom out for zoas
what par and flow are the zoas at

Par about 120, flow is mid tank. Im going to over feed the clowns and snails. That should raise the nitrate level slowly.

Flow and lighting seem to be good so mostly likely lack of nutrients, it’s also worth noting that a ten week old tank can still experience constant minor swings that can stress Zoas but they’re hardy and should pull through just fine.
Happy reefing and good luck!
