HELP!! Green/teal Birdsnest loosing polyps and maybe bleaching...

Hi guys, my new birdsnest start loosing his healty looking polyps, and thoses one in the middle are so tiny and all white... What does that mean ? And also I think the mid part of the coral is too much white...

Setup: 20gal with R420R 60w, 50g skimmer, 20p LR and 20P LS

Alk: stable at 8.5 dKH
Ca: was low (350) at begining, but I just raised it to 430-450 now.
Mg: Unknown because for a stupid reason I broken my test.

I placed the coral where's there med/high water flow on top of my LR.

Some photos:




Any idea ? My frogspawn and zoas look happy.

Did you light acclimate it? Could be getting fried if you didn't.

It looks to be bleaching. I'd move it lower

No, the LFS are using the same light fixture than my... I i run it 8 hrs/day, and it peak at 80%W and 60%B, openine and closing with higher blue than whites.

Should I put it lower in high flow or in moderate ?

Stick it lower in medium to high flow. Always light acclimate because even if it comes from the same lighting it could be higher or lower in the dealers tank and thus receiving different par. I know I've killed acros that were under 400 watt halides because I didn't light acclimate them to my leds.

Ok, I'll try this... I've put it on the sand, the white parts recieve shadows from the upper parts that seems happy. I've lowered overall % of the program on my lights.

Now looks like this

Yeah it didn't look to be dying just really bleaching. Leave it there and then move it up over a week-week and a half
