Brightwell Aquatics XPort PO4 Cubes are a hyper-porous, laboratory-engineered chemical and biological filtration medium designed to bind and remove inorganic orthophosphates and silicates from marine reef aquariums. Utilizing proprietary NanoIntelex technology infused with synthetic Granular Ferric Oxide (GFO), these cubes condense massive adsorptive capacity into a small physical footprint, outperforming conventional granular media by up to 1,000%. They combine high-efficiency chemical extraction with an open matrix that acts as an advanced habitat for beneficial bacteria.
Core Technical Specifications
Chemical Composition: Ultra-activated synthetic ceramic carrier bonded permanently with iron oxide compounds.
Adsorption Capacity: Binds and safely extracts 30 to 100 mg of phosphate per 1 gram of media, dynamically scaling based on your baseline water concentration.
System Longevity: Capable of continuously binding phosphates for up to 1 full year after placement before reaching chemical saturation.
Environmental Constraints: Formulated strictly for aquatic systems maintaining a pH of 7.5 or higher.
Key Performance Benefits
Prevents Coral Chemical Shock: Traditional granular ferric oxide powders can strip nutrients instantly, causing sensitive small polyp stony (SPS) corals to bleach or peel tissue. The structure of XPort Cubes allows for a smooth, progressive drawdown of nutrients.
Zero Fluidization Dust: Because the material consists of durable structured cubes rather than free granules, it eliminates the risk of scattering destructive iron dust or red fines across your display tank.
Dual Chemical and Biological Filtration: While the internal iron complexes trap phosphates, the immense outer surface area of the cubes provides a high-flow home for beneficial nitrifying bacteria.
