Just a pinch of our high grade oceanic salt helps keep your marimo extra green, slime free and thriving! Each order comes in 4oz glass bottle. 

This super fine salt dissolves quickly and easily in water and contains all the major, minor and trace elements needed to recreate a happy, healthy and vibrant aquatic environment for your algae orbs. 

*be sure to keep the lid closed when not in use for optimal salt storage

How much to add? We recommend adding our Marimo Salt to your tap, rain, or spring water at each water change. For regular, ongoing maintenance we add approximately one teaspoon for every 3-4 liters of water. When creating an ocean bath for sick marimo, we recommend mixing seven teaspoons of Marimo Salt for every one liter of water.
