AquaFX Phos-Blaster GFO is a high-capacity granular ferric oxide media engineered for the rapid and efficient removal of phosphate in saltwater reef aquariums. By effectively controlling phosphate levels, this media helps to eliminate unsightly algae breakouts and promotes superior coral growth and coloration. Maintaining low phosphate is crucial for a pristine and healthy reef environment, and Phos-Blaster provides a powerful solution to achieve this stability. This premium GFO boasts a formulation that removes nearly twice the phosphate of standard GFO products, offering superior results and longevity. Its high-density composition allows it to be used effectively in smaller volumes, making it an excellent choice for systems where space is a concern, such as all-in-one aquariums or compact sumps. For optimal performance and to prevent clumping, it is best utilized in a fluidized media reactor, though it can also be placed in a high-flow area using a media bag or filter sock. Phos-Blaster High-Capacity GFO is ideal for the serious reef hobbyist battling persistent algae issues or maintaining ultra-low nutrient systems for sensitive SPS corals. It is particularly beneficial for aquariums with a heavy bioload or for those who need a potent, fast-acting solution to bring high phosphate levels under control quickly. Due to its extreme efficiency, it is recommended to monitor phosphate levels closely when first introducing this media to the system to avoid stripping phosphates too rapidly.
