How to Water and Care for Your Marimo Moss Ball

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.
