I am new to the forum and reasonably new to the hobby so please go easy on me

I’m having a problem with my some of my euphyllia, the skeletons seem to be eroding away. I have researched as much as I can and have found people that have had the same problem but I’m still getting no answers.
I have a Red Sea max nano and my current parameters are as follows:
Alkalinity - 8.5
Calcium - 450
Magnesium - 1440
Nitrates - 10
Phosphates - 0.03
Salinity - 1.026
Temperature - 26
Any advice would me much appreciated, thanks!
