vigorously, watercress should be regularly cut back
hard and since it is nutritious for Koi to eat, bunches of
the trimmings can be thrown into the pond for them to
enjoy. This will add a little nitrogen back into the pond
but when the rest of the trimmings are put onto the
compost heap they will take with them a great deal of
the ammonia, nitrate and phosphate that they have
removed from the water.

Healthy planting around the shower
visually softens its apperance.
