description: This kit includes GFO - 1 lb jar (454 g) Catalytic Activated Carbon - 1.0 lb jar (454 g) 2 mesh filter bags (5.5 X 7.48 Inches) with plastic zippers made with reef tank-safe materials that will not rust. Granular Ferric Oxide Granular Ferric Oxide (GFO) should be used as a part of your tank filtration tools primarily to control phosphate levels. Excess phosphate is one of the main contributors to algae growth, which can quickly become a major problem in a marine system. Controlling your phosphates helps stem current algae issues and prevents future algae outbreaks. This high-performance filter media is made with a premium iron oxide adsorber designed to target and remove contaminants at the molecular level, bringing professional-grade filtration to your aquarium system. With a crystalline α-Ferric oxide hydroxide structure and an exceptionally high surface area, it effectively binds and removes phosphates, helping to prevent unwanted algae blooms and maintain ideal nutrient balance. 🧲 Benefits of Using GFO Removes phosphate (PO₄³⁻) GFO chemically binds with phosphate in the water, effectively removing it from the system and locking it away. Helps control nuisance algae Algae like hair algae, bryopsis, or cyanobacteria thrive on phosphate. Lower phosphate = less algae. Supports coral health High phosphates can inhibit calcification in stony corals (SPS/LPS), making it harder for them to build their skeletons. Keeping phosphate low improves coral growth and coloration. Reduces Tank Maintenance time Reducing phosphates in your tank helps control algae, thereby reducing the time spent cleaning your tank glass.
