A polymer phosphate removal resin that is chemically stable and will not leak any metal ions into the water column like metal-based absorbents.

Slow absorption phosphate removal resin that will not discolor the Water Maxspect Nano-Tech Phosphree is a polymer resin that is chemically stable and will not leak any metal ions into the water column like commonly used metal-based absorbents. The slow absorption rate of Phosphree reduces stress by acclimating the aquarium inhabitants to the reduction of phosphate in the water column.

Maxspect Nano-Tech Phosphree In contrast to the GFO on the right, Phosphree resin will not discolor the water or suspend in the water column.

Lab-Grade Granular Ferric Oxide Granular ferric oxide or GFO will discolor and cloud the water even when rinsed well. Particles often disperse into the water column even when fully saturated with water and filtered by a series of sponges.

500 ml (17 fl oz) of Maxspect Phosphree will remove up to 3 ppm of phosphate from a 2000 liters (528 gallons) marine/reef aquarium.
