BRS Granular Ferric Oxide (GFO) – High-Performance Phosphate Remover for Reef Aquariums

Bulk Reef Supply (BRS) Granular Ferric Oxide (GFO) is a highly effective phosphate-removal media designed to maintain ultra-low nutrient levels in reef aquariums. Phosphate is one of the leading causes of algae outbreaks and poor coral growth, and BRS GFO provides a reliable, chemical solution to control it.

GFO works by binding phosphate directly from the water column, preventing it from fueling nuisance algae and inhibiting coral calcification. Maintaining low phosphate levels helps SPS and LPS corals grow stronger skeletons, display better coloration, and thrive in a stable reef environment.

BRS GFO can be used in media reactors, filter socks, or media bags and is suitable for both nano and large reef systems. It is available in Standard Granular GFO for excellent value and High Capacity GFO for maximum efficiency with less dust and longer lifespan.
