4 t5 bulbs. I guess I will try putting them down lower in my tank.

No zeovite.

I've tried a few different types of Xenia in various spots in my tank over the years and the results are always the same, it withers away into nothing over a period of time. I've even had it flourish for quite a while covering great areas, and then suddenly, just start dieing off for no apparent reason.

Depending on how it is on your rocks, you could try getting some frag plugs and temporarily gluing them to your rockwork, butted right up against the xenia you want to remove which should coax it to attach to the frag plug. Once on that, you can remove the plug and sell the xenia frags.

4 bulbs on a 90 isn't all that bad for light. If the xenia you have is placed near the top then moving it halfway down or lower should help. Also try keeping it in a low to moderate flow area. Mine spreads more when it has less flow on it.
