Neo-Pure GFO Granular Ferric Oxide – Phosphate Removal Media for Saltwater and Freshwater Aquariums – Reduces Phosphates and Improves Water Quality (4.0 lbs)

Neo-Pure Granular Ferric Oxide (GFO) is a powerful phosphate removal media designed for both saltwater and freshwater aquariums. This highly effective treatment tackles phosphates from various sources including base rock, fish food, and organic matter. The media works through molecular bonding to remove phosphates and won't release them back into your water when depleted. For optimal results, use Neo-Pure GFO in a fluidized reactor with gentle tumbling action to prevent clumping, or place it in a media bag in a high-flow area of your sump or filter compartment. This versatile product is suitable for multiple applications including planted tanks, koi ponds, natural swimming pools, and reef systems. Regular use helps maintain optimal water quality and protects aquatic life from the harmful effects of elevated phosphate levels. The 4.0 lbs package offers long-lasting performance, typically requiring replacement every 4-6 weeks depending on your system's needs. Simply rinse before use until water runs clear and monitor phosphate levels to determine when replacement is needed.
