Marimo Moss Ball Aquarium Setup Guide

What You’ll Need:

  • Marimo Moss Ball Aquarium Kit
  • Dechlorinated or spring water
  • A clean surface to work on


  1. Prepare the Water:

    • Fill a clean bowl with dechlorinated or spring water. If you’re using tap water, let it sit out for 24 hours to allow the chlorine to evaporate or use a water conditioner according to the package instructions.
  2. Clean Your Marimo Moss Ball:

    • Gently rinse the Marimo Moss Ball under room temperature water to remove any debris or sediment. Carefully squeeze it over the bowl to discharge any trapped air, ensuring it will sink in the aquarium.
  3. Assemble the Foundation:

    • Take the glass aquarium and fill the bottom with the provided bag of river stones, spreading them evenly.
  4. Position the Driftwood and Fossil:

    • Place the driftwood and the Paleozoic fossil amongst the stones in an appealing arrangement. Consider how they will look from different angles.
  5. Add the Marimo Moss Ball:

    • Set the Marimo Moss Ball gently on top of the stones, allowing it to rest naturally in the environment you’ve created.
  6. Fill the Aquarium:

    • Carefully pour the prepared water into the glass aquarium, leaving about an inch of space at the top to prevent spillage.
  7. Seal the Environment:

    • Place the cork lid on top of the glass aquarium to complete the setup. The cork lid will help prevent evaporation and keep out dust.
  8. Final Touches:

    • Wipe the outside of the glass aquarium with a clean cloth to remove fingerprints or water marks.
  9. Placement:

    • Choose a location for your Marimo Moss Ball Aquarium that receives indirect sunlight. Avoid direct sunlight as it can cause excessive algae growth and harm your Marimo.


  • Rotate the aquarium occasionally to ensure even growth of the Marimo Moss Ball.
  • Change the water every two weeks or more frequently if you notice cloudiness.
  • Gently handle your Marimo during water changes to keep it healthy and green.
