Brightwell Aquatics Xport PO4 Phosphate Removal Filter Media, 4L Cubes

Brightwell Aquatics Xport PO4 Cubes are 4L phosphate-removal filter media designed to remove phosphate and silicate from marine and freshwater aquariums with a pH of 7.5 or higher.

• Designed to remove phosphate and silicate — targets these compounds in aquarium water.
• 4L format — provides a substantial volume of cube-shaped filter media.
• High-porosity, open structure with high surface area — supports water flow through the media and adsorptive efficiency.
• For marine and freshwater aquariums at pH 7.5 or above — makes aquarium type and pH part of the suitability check.
• Can remove phosphate for over one year after placement — offers extended phosphate-removal capability.
• Can be used alongside Xport Bio Cubes and Xport NO3 Cubes — fits with these Brightwell Aquatics filter media.

When phosphate and silicate removal are the goal, the media needs to work with the aquarium’s water conditions and filtration setup. Xport PO4 Cubes are made for aquariums across both marine and freshwater settings, with a defined pH threshold to help guide selection. Their porous, open construction is designed to let water pass through the media while providing surface area for adsorption.

How do Xport PO4 Cubes remove phosphate and silicate?

They use NanoIntelex Technology and Ferric OxyHydroxide in a high-porosity material designed for adsorption. Brightwell Aquatics states that this combination gives the media the capacity to outperform conventional phosphate-adsorption media by over 1,000%. The open structure and high surface area support flow-through as well as adsorptive efficiency.

• Active material: Ferric OxyHydroxide.
• Technology: NanoIntelex Technology.

Which aquarium conditions are these cubes designed for?

Brightwell Aquatics Xport PO4 Cubes are designed for marine and freshwater aquariums with a pH of 7.5 or higher. Use the aquarium’s water type and pH as the key criteria when deciding whether this media suits your setup.

• Suitable aquarium types: marine and freshwater.
• Minimum pH condition: 7.5.

How long can the media remove phosphate, and can it be paired with other Xport media?

After initial placement in the aquarium, the cubes are capable of removing phosphate for over one year. They may also be used in conjunction with Brightwell Aquatics Xport Bio Cubes and Xport NO3 Cubes.

• Duration claim applies to phosphate removal after initial placement.
• Compatible companion media: Xport Bio Cubes and Xport NO3 Cubes.

These cubes suit aquarium keepers seeking phosphate and silicate-removal media for a marine or freshwater system that meets the stated pH condition. Their 4L format, porous construction and compatibility with other Xport media make them a defined option for aquarium filtration focused on phosphate adsorption.
