Phosfiltrum

Aquavitro Phosfiltrum™ is a high-capacity granular ferric oxide (GFO) media designed to rapidly remove phosphate and silicate from both freshwater and saltwater aquariums. By lowering excess phosphate, it helps reduce nuisance algae growth, improve water quality, and support healthier corals and aquatic life. Its dense, durable formulation resists breaking down into fine particles and offers exceptional phosphate-binding capacity for long-lasting performance.  

For reef aquariums, Phosfiltrum is an effective solution for maintaining low nutrient levels and promoting optimal coral coloration and growth.
