sad violet

My largest african violet has suffered. It leans to one side, lower leaves wilting.

I trimmed off the dying foliage and completely repotted it, in a smaller container with new soil. The stem below soil level had a lot of white crust on it probably deposits from our hard water. I don't know if that was part of the problem, though.

I put it back in the same location by the guppy tank, but it might need to live in a different spot.
