Bayoxide Phosphate Remover Granular Ferric Oxide (GFO )
Phosphorus is one of the basic building blocks of living matter. It is present in every living creature, and in the water of every reef tank. Unfortunately, it is present in excess in many reef tanks, and that excess has the potential to cause two big problems for reef keepers.
- It can stimulate excessive growth of undesirable algae.
- It can directly inhibit calcification by corals and coralline algae.
Since most reef keepers don’t want either of these things to happen, they strive to keep phosphorus levels under control. Most phosphate comes from three sources: tap water, fish food, and carbon. In the case of city water, the municipality may actually be adding it to protect its pipes. In well water, phosphate often come from the leaching of lawn and garden fertilizers.
Replacement water can also contain phosphate, sometimes surprisingly high concentrations, even if RO units are in use.
Additives such as pH stabilizers or carbon, and frozen fish food are potential external phosphate sources. Avoiding phosphate containing products as well as testing of the replacement water for phosphates can further help prevent accumulation. If in doubt, additives, carbon, pH buffers, and the water should be tested and replaced if necessary.
Prohibiting phosphates from entering the water or from forming within the aquarium is the best safeguard from the harmful consequences of accumulating phosphates.
Inorganic phosphate or orthophosphate is the soluble form. It is readily available and quickly absorbed by plants. Organic phosphate refers to phosphate that is part of a cell structure or organically bound in other ways. Organic phosphate must be broken down by bacteria in order to become soluble orthophosphate.
The biggest source of organic phosphate is fish food. 5 grams of flake food can increase the organic phosphate level by 0.4 ppm. The filters and substrate have to be cleaned regularly before the organic phosphate is mineralized to inorganic orthophosphate.
To avoid unwanted phosphate levels, make sure no uneaten food is allowed to remain in the aquarium. To reduce or eliminate phosphate already present, commercial phosphate removers can be effective. Of course, an excellent way to start is by using water purified through reverse osmosis (RO), and then using it for regular water changes.
About Granular Ferric Oxide
Our Bayoxide Granular Ferric Oxide is a very pure form of Ferric Oxide that will absorb phosphates in your aquarium without leaching any iron ions into your tank. Use of Granular Ferric Oxide (GFO, or iron oxide hydroxide) is a popular and effective means to reduce reactive phosphate (a non-metal) concentrations in aquaria hence reducing the potential for algal growths. Silicate (a metalloid) is also efficiently removed. It is known that GFO can also remove a number of transition metals (such as zinc, copper, manganese, etc.) For best results use a fluidised reactor when using GFO.
- 4x higher phosphate removal compared to standard GFO.
- High mechanical strength and low dust content.
- Arsenic removal from potable water in which both, arsenate As(V) as well as arsenite As(III) are safely adsorbed below 5 μg/L.
- Antimony, vanadium, and selenium removal from potable water
- Heavy metal removal from potable water, e.g., copper, lead, nickel, and zinc
- For use in Saltwater, Freshwater, and Ponds.

- Rinse before use.
- Use 1/4 to 1/2 cup per 50 gallons for saltwater aquariums.
- Test phosphate levels and replace media when levels begin to rise (approximately every 1-3 months).
- As with all ferric oxide media, alkalinity levels may drop when used. Be sure to monitor alkalinity and adjust as needed
