Fluval Moss BallA1344
The Fluval Moss Ball helps create ideal aquarium conditions for small fish and shrimp by adsorbing and trapping phosphate and nitrite. It also helps reduce aquarium maintenance by deterring the growth of many of the compounds that cause the unsightly buildup of organic matter. The Moss Ball also serves as an attractive decorative addition to aquariums. Designed for freshwater shrimp or fish aquariums, it is effective for up to 2 months and treats 30 to 60 L (10 to 20 U.S. gal.) aquariums.
