Buy Bulk and Save. no point paying more for a sticker and a fancy container when you can buy our high quality bulk Granular Ferric Oxide (GFO). The only difference between this and the name brand GFO is the packaging.

GFO is design to stop algae growth by removing phosphates from the aquarium. They are also effective at removing a wide range of pollutants including nitrates, sulfides and other harmful chemicals from the water source.

Maintaining low phosphate levels will help prevent algae outbreaks and help promote faster coral's growth. Once exhausted GFO media is non-hazardous and wont leak chemicals back into the aquarium.

Features: Removes phosphates, arsenic and heavy metals. Works best with media reactor (For example: BM Mini Reactor) or place in a mesh bag in a high flow area or filter.
