My coral is whitening

[didou]

I'm actually not sure it's an sps or LPS, since 3 days the bottom part of the coral is starting to retract and die. (The top part of the coral is dead since I got it 2 months ago and the post isn't about this part. I planned to cut the coral in half to get rid of the top part before but never did it)

My parameters are stable and except phosphate everything is fine (I'll write then down after).

It's in the bottom of a 1500 liters tank and I have reefleds 160 5inch above surface. The tank is 80cm tall. And it's 4 years old.

Do you think not enough light and the coral could die that quickly? 3 days ago there was no white part and the coral was fine. I think I should move the coral higher, but could there be another problem not related to light (because I lost an acro too, whitening from the base).

I recently added a 180 liters frag tank in the same system and I just had an algae boom only in the frag tank but now everything is fine.

Parameters:
Salinity: 10245 (usually 1025 I will make new water today)
Kh : 8
Ph: around 8.1/8.2
Nitrate: always between 6 and 10
Phosphates: 0.13 (usually 0.08 but sometimes it spikes to 1.15)
Calcium and mag are always ok and I rarely test (I do an icp every 40 days)

LPS, unsure exactly what, though.

test calcium.

Is it a Platygyra? Regardless it's an LPS that does well under lower lighting with mod flow. That's a lot of light for that coral.
Could a fish or inverts be eating it?

My son and I had the same issue because we just did not know what WE WERE Doing am not accusing you of that but I recently bought quite a few coral all easy level Low to medium light, and flow. Ever want to educate yourself go to a site Candy Corals , I also for the first time am dosing by adding trace elements. Noticed a huge difference in coral growth, and health. Check Par with a meter my suggestion

It looks like a lord acan to me (micromusa)... they are an lps, fairly hardy. If you've only had it 3 days and its dying like this, I would move it, try a different location in the tank.

The sps whitening from the bottom sounds like rtn, which unfortunately happens sometimes, I would say not related to this case.

Thank you guys

test calcium.

Calcium is at 440

Hope you will update us with your choice of actions and the result??!!

I changed the location but it is still progressing, it's almost completely dead now :(

There is white "bubbles" that seems to eat the rest of the alive coral, is this a disease or something else eating my coral?
