Product details
Xport PO4 Cubes – Brightwell Aquatics are phosphate-adsorbing cubes for use in marine and hard freshwater aquariums with a pH of 7.5 or over. In practice, they help reduce dissolved phosphate so you can support clearer water and help manage nutrient buildup from feeding and natural waste. Use them as a filtration media option when you want phosphate control via adsorption.
Features:
- Designed for marine and hard freshwater systems with pH 7.5 or higher
- Uses NanoIntelex Technology to create an “ultra-activated” material for phosphate adsorption
- Outperforms conventional phosphate-adsorption media by over 1,000% (per the stated comparison)
- Open structure and high surface area support strong flow-through characteristics and efficient adsorption
- Reported phosphate removal of approximately 30–100 mg per 1 g of media (dependent on initial phosphate level)
- Higher adsorptive capacity can reduce the media quantity needed for equivalent uptake
- Capable of removing phosphate for over 1 year after initial placement (as stated)
- Can be used alongside Xport Bio Cubes and Xport NO3 Cubes for broader nutrient management
