(long sigh) Watercress is for munchies. Besides, it doesn't like 82* water -
I already tried.

Lee, maybe getting some watercress from the grocery store would be the
quickest way to reduce your phosphates. One year I suspended a mesh
basket under my waterfall (above pond surface), threw in two bunches of
watercress from Safeway, and let the roots grow over out through the
mesh into the water. My algae cleared quickly that year and stayed away.
(Note to self: replace watercress that koi pulled out of net ring and
ate!!)
