I added the Fluval Moss Ball to my shrimp tank and noticed less algae growth within a week. It looks great and doesn’t interfere with the water chemistry. My shrimp seem more active and the water clarity improved noticeably.

The moss ball has been in my aquarium for over a month. It’s still intact and the water looks cleaner than before. I didn’t have to do as much water changes. A small but effective addition.

Great for a small tank. It’s not just decorative—it actually helps keep the water cleaner. My tiny guppies are thriving, and the algae problem has reduced significantly.
