If the plant in your tank turns yellow, it's most likely that the plant has died.  Please contact us for warranty information for the plants.

For the safety of the BioSphere, you want to remove the plant.  The plant can be easily removed from the tank by gently pulling it straight up.

The plant is an essential part of the Nitrogen Cycle and adds to the beauty of their habitat!

You can replace your plant with any 4 inch Lucky Bamboo, Java Fern, Sagittaria Grass, or anubias - that you can typically find at a local nursery. To add it back, push the plant down into the gravel/sand with your fingers, tucking the roots into the sand.  Once it has hit the bottom of the tank, gently push the decorative rocks and gravel around the plant to hold it in place - while the roots grow into the colored gravel and sand.  It's okay if some of the roots are exposed.
