NEED HELP BACK AFTER 4 MONTHS

[THE REEF WHISPER]

Hey everyone, I’m back after a long hiatus. Life got insanely busy the past several months and my reef tank unfortunately took a backseat. I finally have some time again and jumped back in today… wow, what a change. The tank definitely suffered while I was gone some corals are stressed, a few have taken a hit, and overall it’s not where it used to be. I’m determined to bring it back to life and get it thriving again like it once was.
Any advice, encouragement, or similar comeback stories would be greatly appreciated as I start this recovery journey. Thanks in advance!

Here are some pictures

The system seems to be doing fine after a day but will still keep an eye on it

I have a question too in the Evo 13.5 gallon can I but BTA ONLY AND GET MULTIPLE AND MAKE IT A NEM TANK

You want to make your Evo a 'nem tank? Might be a bit small for BTA's, I think a bunch of Rock Flower Anemones would look great, I'm hoping to do that with a 15 gallon.
