My xenia looked really bad when I moved it from my 46 to my 110. I almost got rid of it, too, but I really like the way it moves and pulses.

So I kept it and started adding some Seachem Reef Plus. I don't know what it has, maybe Iodine, but the xenia really perked up after I added it for about 2 weeks. I would say that the xenia almost doubled in size. All the trunks are a lot thicker.

You might give it a try.
