  • Double the Adsorption Capacity: Elite high-density iron matrix binds up to two times (2×) the orthophosphates and silicates per volume compared to standard GFO.
  • Generous 5.75-Pound Utility Size: Large-capacity utility jug with a wide-mouth handle cap is scaled perfectly for high-volume sump filtration loops or routine large-scale media swaps.
  • Resists Friability & Attrition Dust: Hardened granule structure exhibits superior structural strength, drastically minimizing the creation of fine red fines during transit and fluidization.
  • Perfect for High-Bioload Systems: Aggressively targets and strips away the primary food source required by invasive green hair algae, cyanobacteria, and diatoms.
  • 100% Aluminum-Free Composition: Pure iron-oxide formulation guarantees zero toxic aluminum leaching, keeping delicate SPS corals and marine invertebrates fully safe.
  • Space-Saving Reactor Footprint: Because you only need to use half the volume of standard media, it saves valuable physical space inside compact fluidized upflow filters.
