What should I do to help my yellowing watervine plant?

The green mold in the water is algae or bacteria. TSU Extension Agent Joellen Dimond asks if the plant has enough light or nutrients. Water by its self does not provide enough nutrients to sustain a plant. Master Gardener Tom Mashour says he adds a weak solution of fertilizer to the bamboo he grows in water, and it is healthy. He recommends the same here.
