Had the same occurrence.
Only that one coral, nobody else, stable 5 years.
No crabs, no shrimps…..strange.

Should I stick it in my sump for awhileas some like dirty water ?

I don't think it's particularly happy. How is your lighting, flow and water parameters?

all good as stated from above lighting is great

0.4 phosphates is high !!!
2 nitrates is low

I dont see any skeleton or recession, are you sure its not doing well?

That calcium is kinda low for my tastes, personally I find corals do better at least 420ppm or more. The color looks a bit washed out, your nitrate is pretty low too. I try to aim for at least 10ppm to 40 with most open brains.

Did a couple of water changes but it not really spread out to say almost looks like it is closing up but will wait and see
0.2 phosphates
6 nitrates is low

could just be irritated, unless you start seeing obvious recessions or skeleton, I think its fine for now.

Phosphates should be around .05 -.08 , nitrates around 10 . At this point you brought the phosphates down rather fast , just let it be for now except maybe bring up the nitrates a little . Patients is key steady and slow . Just try to keep your parameters in check and keep them steady . Try not to let your phosphates get that high again . I wouldn’t put it in the sump .

water changes were about 3 days apart so not to change prams too fast thaks for the reply every thing helps first donut coral I evert had

Thanks for the tips will try

Need to get some hanna checkers my API kit is expired my bad 2 new checker on the way Phosphates checker and a nitrates checker off to LFS
