Water changes

Marimo moss loves water - especially clean water - so whether you keep your pretty Marimo in a bottle, bowl or in an aquarium, you need to change the water from time to time.

Make sure the water temperature never gets higher than 25 °C / 77 °F. If necessary, you can actually place the bottle/bowl in the refrigerator during the warmer months. — Planta tip

If your Marimo lives in a bottle/bowl

• Carefully lift up your Marimo moss ball and place it in a safe spot

• Pour out all the water and, if needed, clean the bottle/bowl

• Fill your bottle /bowl with clean tap water

• Carefully roll your Marimo between your hands

• Clean your Marimo ball by rinsing it under a soft jet of water or by gently squishing it a few times in a bowl of clean water.

• Put your Marimo back in the bottle /bowl

If your Marimo lives in a filtered aquarium

• Carefully lift up your Marimo moss ball and place it in a safe spot

• Pour out 25% of the water and if needed, clean the aquarium

• Fill the aquarium with clean tap water

• Carefully roll your Marimo between your hands

• Clean your Marimo ball by rinsing it under a soft jet of water or by gently squishing it a few times in a bowl of clean water.

• Place your Marimo back in the aquarium

Tap water usually works just fine, but if your Marimo is placed in an aquarium you also might want to dechlorinate the water. — Planta tip
