Bayoxide® E33 GFO (Granular Ferric Oxide) Phosphate Reducer fights harmful algae in fresh and saltwater aquariums by eliminating their phosphate food source. Left unchecked, high phosphate levels and algae can cause extensive harm to fish, coral and other aquarium life.  

Our high-quality, virgin, drinking water grade GFO phosphate reducer adsorbs phosphates more quickly than competing phosphate removal medias - and keeps them away longer. The result? Clearer water, a healthier tank environment and less time spent cleaning your aquarium.


  • Removes phosphates quickly on contact
  • Also removes silicates, arsenic and many heavy metals
  • Reduces and prevents algae growth
  • High phosphate removal capacity for lasting efficacy
  • Creates a healthier environment for aquatic plants and animals
  • Safe for all fresh and saltwater aquariums, reef tanks and ponds
  • Highly effective in reactors, filters socks, canister filters and filter cartridges
