Hello I am new to reef keeping. It seems there's many knowledgable reefers on this forum. I would like your help to understand what is happening to the frag. I had it in my tank for three weeks and it seems doing fine until I noticed some of the pores are missing/bleached? The frag was placed in mid lvl of the tank and now moved to the bottom. I think it might have to do with light, but what do you guys think?
SPS Dying?

It looks like green birds nest to me also. Sps in general dont like swings of any type. Salinity or alk swings with for sure cause rtn and stn issues, tissue necrosis. In my experience they like stability and higher salt level. 1.025 or so. Mag can be an issue also if it is to low. Hope any of this helps. Good luck. Happy reefing.

I agree.. It didn't look like the normal "birdsnest" I've always seen... Which I believe is Seriatopora hystrix which is far more "pointy" in the tips vs the seriatopora gutattus..
Its so hard to tell some of them apart sometimes..
No matter..

He said he's had it in the tank for 3weeks. Not that the tank is 3weeks old.

Looks perfectly fine to me. The polyps are an off colored white, but they're still full extended around what looks like 100% of the coral. Doesn't look to me like there's a single thing wrong with it.
Edit: If you want to see what I'm talking about you could lightly brush it with something so it retracts the polyps. Almost guarantee the white goes away. Do it at your own risk though haha

Thanks for all the responses. Clearly there is much to learn here.
@Percula9 - I do water change every week about 10 to 15%. I get the filtered water from Safeway and mix my own salt. Maybe I should test the phosphate and nitrate level of the water from Safeway.
@mcgyvr - This is a 14 biocube with stock lights. I did not check the ALK/CAL level because I do water change every week and only have two frag in the tank so far. Thought it wouldn't matter that much. But I do notice the tank temperature can get pretty 80 to 82 due to the heat from the light. Maybe this is the cause?
From my understanding (browsing through the forum), that stock light from the Biocube gives 100 to 200 par (bottom to top), while SPS usually requires higher par usually upper 300. Would you agree that lighting is not the issue?

You need to check alk Calc and mag, most important being alk

He said it's been in his tank 3 weeks.. not the age of his tank.
To OP, we need to see your water parameters.
