Brightwell Aquatics FerroxiPhos G

Overview

Brightwell Aquatics FerroxiPhos G is a granular ferric oxide (GFO) media designed to rapidly and safely remove phosphate and silicate from marine, reef, and freshwater aquariums. By lowering excess phosphate, FerroxiPhos G helps prevent nuisance algae, improves water clarity, and supports stronger coral and invertebrate growth. Its dense, low-dust granules are ideal for use in media reactors or filter bags and deliver long-lasting performance without impacting essential trace elements.

Key Features

  • High-capacity granular ferric oxide media for phosphate and silicate removal

  • Helps prevent and control nuisance algae outbreaks in reef and freshwater tanks

  • Supports healthier corals, invertebrates, and plants by maintaining low phosphate levels

  • Low-dust granules—minimal rinsing required before use

  • Will not release absorbed phosphate back into the water under normal conditions

  • Chemically stable and free of binders, resins, or added organics

  • Suitable for use in media reactors, canister filters, or filter bags in sumps and overflows

  • Safe for all marine, reef, and freshwater systems when used as directed
