Ok, Lissa. A couple of things to consider. Your tank looks deep. How deep I do not know. Some dimensions would help. Generally, Zoa's and the likes prefer lower to moderate lighting and flow and the same goes for your shrooms. Place them closer to the mid to lower portions of the tank with moderate flow. The Favia also likes moderate lighting and the lower the flow the more likely it will puff out. You still need enough flow but not too much. It's a balancing act. Might take a bit to get it dialed in. The overall tank color looks better. If you want to ramp up the intensities, do so over time and incrementally. Xenia, I have seen run the gamut in the lighting scheme of things so just wait and see. They do prefer moderately low flow to get them to pulse. Shrooms can and sometimes do move, but not often.
It is wise to test your Alk and Ca and keep them within normal seawater parameters. While the Xenia, Paly, Shrooms, and Zoas may not utilize calcium and alkalinity we want to keep and maintain water parameters as close to Natural SW as possible.
You want to, ideally, have "0" TDS makeup water. Do what you can to get it there.
Once you have made some changes, stop, don't change anything and see how things progress and/or digress over the next week or so. Give your corals time to acclimate, they just went through quite a change but, giving them ideal living conditions should allow them to bounce back. Corals are incredibly resilient and confounding at the same time. Try to respond to coral behavior changes after proper investigations and observations instead of reacting to them.
What is your water temperature? And, get quality test kits to determine you Ca & Alk.
