Trumpet coral bleaching?

[xitto]

Hi

I upgraded my reef this weekend to a bigger 50 gal tank. New lighting marsaqua 300w (dimmers are 20% blue, 10% white now)

All my softies look great with new lighting but the trumpet coral is expelling zooxanthelles, the inner side is turning transparent..

Sorry, picture is awful...

is it bleaching? or just adapting?

We would only be guessing without further info. Lighting, params, etc. A new tank could mean anything. Was it new? Copper ever in it? etc. etc.

Sorry.

It's a new upgrade to a 50 gal tank.

Params are:
5 ppm no3
0 no2
salt 1025
alk 9
Lighting: chinese marsaqua 300w. Dimmers are just 20% blues, 10% whites

Fishless and skimmerless (yes, i know it's strange but i like corals, not fishes[emoji4] )

Just a few softies as yet, trumpet coral and tons of pods.


I did the upgrade three days ago, today trumpet coral is looking much better... so i assume it is just adapting. Green color is back and it is fatter than yesterday..

Thanks!
