Fluval foam ball. 4.5 cm in diameter.

The Fluval foam ball absorbs phosphate and nitrite, helping to create ideal water conditions for small fish and shrimp.

This moss ball also helps reduce maintenance, as it prevents the proliferation of several compounds that cause unsightly buildup of organic matter. It is also a beautiful decorative element in aquariums.

Effective for nearly two months, it is designed for freshwater aquariums containing 30 to 60 L (10 to 20 US gal) of water and intended for shrimp or fish.
