How To Care For Marimo Moss Balls (And Keep Them From Turning Brown)

WHAT IS A MARIMO MOSS BALL?

A Marimo Moss Ball isn’t actually a moss! Marimo Moss Balls are actually a cylindrical algae from the colder waters of Japan and Iceland.  They grow about 5mm a year and can last 100+ years

HOW TO “REFRESH” MARIMO MOSS BALLS

STEP 1:  REMOVE FROM YOUR TROPICAL AQUARIUM

STEP 2: CLEAN THEM

I usually fill a container with tank water or clean dechlorinated water and squeeze them and roll them.

STEP 3: DUMP THE WATER, AND FILL THE CONTAINER WITH FRESH DECHLORINATED WATER

STEP 4: STICK IN YOUR FRIDGE

Some people leave them in the fridge for a few hours, some overnight, some for a few days.

STEP 5: PLACE BACK IN TANK!

That’s it! Now you have fresh, dark green, healthy Marimo Moss Balls in your tropical aquarium!
