AquaFX Phos-Blaster GFO is a high-quality granular ferric oxide filter media designed specifically for saltwater reef aquariums. Its primary function is the efficient removal of phosphates from your tank water, which are a major contributor to nuisance algae growth. By actively adsorbing phosphates, this media helps to prevent and even reverse existing algae outbreaks, ensuring a cleaner and healthier aquatic environment.

This particular GFO formulation is less dense compared to high-capacity alternatives, making it exceptionally well-suited for superior tumbling performance within a fluidized media reactor. This characteristic ensures maximum contact time with the water, optimizing its phosphate-binding capabilities. The 1 lb quantity provides ample media for effective long-term phosphate control in most reef systems.

AquaFX Phos-Blaster GFO is an excellent choice for reef keepers aiming to promote vibrant coral growth, including both SPS and LPS corals, by maintaining ultra-low phosphate levels. It is ideal for hobbyists who utilize a fluidized media reactor and are seeking an effective, easily tumblable GFO to combat algae and support a thriving, crystal-clear reef tank. Regular phosphate testing is recommended to monitor its effectiveness.
