potash, and it is my understanding has nothing to do with pH. OK,
I'll try the potash too. As soon as I send this and tear myself away
from the chair.

What is your pH and what kind of filter plants (Not potted.) do you
have that are green and growing? I'm not against trying another plant
as a filter plant, I've just had good luck with water hyacinths most
years, but some years they don't grow in my pond.

Hi Hal,

As mentioned my pH is over 8. I grow water hyacinth and parrots feather both
of which thrive in my pond. The only problem I have is my hyacinth doesn't
too thrilled about blooming. Nitrogen is typically what "greens" things up.
Try taking them out of the pond and place them in a container with
fertilizer to see if that helps.
