Jawbreaker not doing well

[maxwell50]

Hello I had a mama jawbreaker for a while now. Everything was good and I run high nutrient level. I did big water change about 50% to bring down phosphate and raise alk. My prewater change Alk was at 7.6 and after water change 8.5 so it spikes about 1 dkh. My phosphate was at .9 ppm and now it’s at .8ppm so not much change here cal is about 450 and mag about 1350. I’ll post pre and post pics and can anyone tell me if there is something I can do to save the shroom. All other corals are doing well and my acans never looks so puffy
Thank you.

It maybe just upset due to the water change. Observe it for a bit for doing anything drastic. I have about 40-50 jawbreakers and they can tolerate a very large range of parameters before dying.
