I guess it mewans 'too' clean water. I know that I need to keep my
3/4 acre pond NOT clear with nutrients for the bass and brim to have
food! There we put in missing nutrients if the water gets too clear.
My koi pond is totally clear. I guess the hyacinths can't compete for
the limited nutrients and the ones in the shallow pond below the falls
can get to nutrients. Hmmm...the water celery has muck beneath it. I
can try to put some hyacinth in that pond to see how they do. I could
also chuck some of the water lettuce that is thriving.

If you put WH where its roots dangling into soil, it will green up.... at
least it has for me. I did mess with any WH this year. ~ jan
