Xenia Not Pulsing/Opening

[cameronh21]

My pulsing Xenia has not opened or pulsed in about 2 weeks and I am a bit concerned since it was doing so well before.
2 things changed:
I did not do a water change in 5 months prior to two weeks ago so maybe the change in dirty water to clean water.
Also prior to the water change my salinity was always 1.025 and it has been 1.026 since then but now today I got it back to 1.025.
Also I don’t know my levels as my reef tank is on a very tight budget.
Do you think these things could be the reasons? If not what can be done about this? Any help is appreciated, thanks!

You should start by testing your parameters.
Macros first. Alk cal mag. Could have been from a sudden swing.
