I have a small (250 gallon) pond, with an approximately 10 gallon
upper
pond, that feeds water down a waterfall into the main pond. In the past
I
have used water hyacinths in the upper pond to "strain' the water, and
it
has worked well. Are there other floating plants that could be used in
the
same way - just for a little variety?
===============================
Water lettuce is nice. I use it in my settling tank. They get huge.

The WH are the better plant for filtering. The roots are much denser then
the lettuce, but the lettuce are a close second. Ingrid has had great
success with water celery. That would work too. Watercress is cheap, and
also grows very dense in moving water.
