AquaFX Phos-Blaster GFO High-Capacity is a premium granular ferric oxide filter media designed for exceptional phosphate removal in saltwater aquariums. This powerful media efficiently controls and eliminates unsightly algae outbreaks, ensuring your tank remains pristine while promoting superior coral growth and overall reef health.

This high-capacity GFO removes nearly twice the phosphates compared to standard Phos-Blaster GFO, with results often surpassing other leading brands. Its increased density allows for effective use in smaller volume applications, making it ideal where space is a concern. For optimal performance and proper tumbling, an AquaFX fluidized media reactor is recommended, though it can also be used effectively in media bags or filter socks.

This product is ideal for reef aquarium enthusiasts committed to maintaining low phosphate levels and preventing nuisance algae. Hobbyists seeking to maximize coral vibrancy and growth will benefit from its efficient nutrient export capabilities. Its high performance and compact nature make it an excellent choice for any reef keeper prioritizing a clean, healthy, and thriving aquatic environment.
