If I remember correctly, the first time I read about water hyacinth being put in a koi pond, was in a thread by Maurice. He even posted beautiful pictures of it with flower in full bloom. Now, I noticed in recently posted pictures of Momotaro auction that there is water hyacinth in both indoor and outdoor ponds.
How beneficial is it actually to pond water? Does it reduce nitrite/nitrate level just like other plants? Or is there any other function?
