Chalice coral bleaching

[Jeremy Brito]

Hey guys I was wondering if any of you could help me pin point the issue with this chalice.
Today I found a white spot on my Hollywood stunner chalice it didnt look like that yesterday the only thing I can think of was how I added some alk buffer solution to the tank tester day but it didnt look like it was the cause cause the chalice sits under neath a power head that blows everything away
The parameters in,the tank are as follows
Alk 9.2
Temp 78.6
Mag 1350
Cal 450
Phosphates trace
Nitrate 25
Ph 7.5 ( my concern)
Any ideas

What's your salinity? it looks like it's dying

Its the lighting aside from the bleach spots the rest looks,extremely healthy.
Salinity is 1.026

It's dying, try to frag that white part off to see if you can save it

Ok

Any spikes in Alk by chance?

Nitrates seem high IMO.
Agree PH is low but if it's stable I would not worry about it.

that doesn't look like bleaching. it's dying. you could dip it in iodine. i had a chalice that started to lose some flesh and i did he iodine dip and it stopped it and everything grew back in a few weeks.
