Granular Ferric Oxide (GFO) Phosphate and Arsenic Reduction Media

Granular Ferric Oxide (GFO) is a high-performance dry granular media that is designed to effectively remove phosphorus, arsenic, and other heavy metals from both freshwater and marine environments. Its high surface area and porosity make it an ideal adsorption medium that promotes healthy aquatic ecosystems by preventing algae growth and enhancing water clarity.

Key Features & Benefits

• High Adsorptive Capacity – Rapidly removes phosphates, arsenic, and heavy metals without leaching back into the water.

• Versatile Applications – Suitable for freshwater aquariums, planted tanks, koi ponds, natural swimming pools, hydroponics, saltwater aquariums, and reef tanks.

• Safe for Aquatic Life – Does not release adsorbed substances, ensuring the safety of fish, invertebrates, plants, and pets.

• Easy to Use – Can be placed in mesh media bags or fluidized reactors, compatible with various filtration systems.

• Long-Lasting – Requires minimal maintenance and can be used for extended periods before replacement.

Easy Operation

• Place the GFO media in a mesh media bag or suitable filtration reactor.

• Rinse the media before use until the water runs clear.

• Replace the media when phosphate or arsenic levels begin to rise, typically every 4–6 weeks.
