Water hyacinths are one of those miracle plants that filter water very
well. I seem to remember reading they can do a number on metals as well.

Unfortunately, I have never had luck bringing them indoors. There is a
perennial thread in rec.ponds on this subject and it seems that no one has
been able to keep his water hyacinths consistently alive
indoors--regardless of lighting arrangement, temp, etc.

If anyone has had better luck, please let us know what you did.
