Xport-PO4 Phosphate Absorption Media

Xport-PO4 is great for tanks that have minimal aquascape, or are heavily stocked. Brightwell utilizes NanoIntelex technology to create a highly superior biomedia packed with ultra-activated phosphate removal material. The biomedia cubes can be put just about anywhere within the system to allow more surface area for biological filtration, resulting is faster removal of phosphates. Bacteria will colonize on surfaces within the aquarium, and by adding an ideal growing medium, the bacteria can flourish, resulting in efficient processing of wastes in the aquarium.

The cubes have a vast amounts of surface area that will allow beneficial bacteria to colonize. Xport-PO4 works with all types of saltwater aquariums and can be employed in just about any fashion that doesn't tumble the cubes. Xport-PO4 is a superior biomedia that is one of the most adaptable phosphate removing biomedia cubes on the market today. Made specifically with ultra-activated materials that have the ability to easily outlast some of the most advanced phosphate removal medias out there.

• Utilizes NanoIntelex Technology to create an enhanced, "ultra-activated" material with the capacity to outperform conventional phosphate-adsorption media by over 500%
• Removes ~30 - 100 mg phosphate per 1 g of media, dependant upon initial concentration in system.
• Open structure and high surface area results in superior flow-through characteristics and adsorptive efficiency.
• Higher adsorptive capacity relative to conventional media results in smaller space requirements to achieve equivalent phosphate uptake.
• Capable of removing phosphate for over 1-year after initial placement in aquatic system.
• May be used in conjunction with Xport-BIO and Xport-NO3.

Instructions and Guidelines

Read all instructions before use. The use of a mechanical pre-filter to remove particulate organic material from water prior to its interaction with this media will improve efficiency. Rinse Xport-PO4 in purified water or low-TDS fresh water, then place media into a clean pail and fill with water from the aquarium into which the media is to be placed. At an initial phosphate concentration of 1 ppm or less, 350 g of Xport-PO4 is capable of extracting ~10.5 g of phosphate; this equates to 1 g of Xport-PO4 per 396 US-gallons (1,500 L) to eliminate 0.02 ppm phosphate. Replace media when phosphate concentration ceases to decrease (if greater than 0 ppm) or begins to increase. In low-nutrient aquaria, it is not uncommon for several months to pass before the media has become exhausted. If corals or other invertebrates appear to react negatively to the use of the media, it may be an indication that reactive phosphate is being removed too aggressively; decrease amount used by 50% and continue use until phosphate concentration appears to be immeasurable. The most efficient use of Xport-PO4 will rely upon regular testing for phosphate with an accurate test kit to ensure that the mass of media being employed is suitable for the system requirements.


A flow-through rate of 1 - 3x the total aquarium volume per hour is recommended. Do not fluidize; fluidization serves to decrease filtration efficiency and may cause gradual deterioration of the material, potentially resulting in dispersal of harmless, but unattractive, dust throughout the system. Canister filtration: Load Xport-PO4 into filter cartridge as directed by filter manufacturer. Passive filtration: Place Xport-PO4 loosely in an 800µm mesh filter bag and locate in an area of low- to medium-flow. Media reactors: If placing Xport-PO4 into a media reactor, ensure that the media remains "static" and non-moving.
