xenia wilting

[jpierson77]

The otherday I came home to find some of my xenia had dark streaks down the middle some of the what i would call the "petals". Over the coarse of the last couple of days they have begun to wilt up and become darker. Any ideas? all params. look good I did just switch lighing form 2 150 w hqi's to two 400w se's. COuld this be the problem, everything else appears to be doing well.

I would suspect the lighting change to have something to do with it. Especially if your water params indeed check out and nothing else has changed.

Try placing the xenia lower in your tank. They might be wilting due to excessive light exposure.
