Fluval Moss Ball

The Fluval Moss Ball is a dual-purpose accessory that quietly cleans your water while adding a natural, mossy accent to the tank. It adsorbs and traps phosphate and nitrite to help hold ideal conditions for small fish and shrimp, and it discourages the organic buildup that leads to unsightly film and grime. Drop it into a shrimp or nano setup and let it work. Rotate it in alongside your other filter media.

How to Use

Rinse the Moss Ball and place it in the aquarium or inside your filter where water flows around it. It stays effective for up to about 2 months, so swap in a fresh one roughly every 2 months to keep phosphate and nitrite in check. One ball suits a tank of about 10 to 20 US gallons.
