Product Description

PhosBan from Two Little Fishies is a favored chemical filter maedia because it will not leach substances back into your aquarium. Largest adsorption capacity of any phosphate filtering media. Ferric oxide hydroxide-based granules also adsorb organics and other pollutants. Use just like activated carbon; filter bag included. Non-toxic and lasts several months in typical aquariums. Great for saltwater and freshwater aquariums. This product comes highly recommended by Aquacadabra. For best results, use with the PhosBan Reactor.

150 gram jar is 0.33 lb, includes a filter bag, and treats 150 gallons.
1,200 gram bulk size includes filter bag and treats up to 1,200 gallons.


PhosBan can be rinsed briefly before use, but since it is friable, do NOT stir the granules, which would pulverize them. Put PhosBan in a tightly-packed media bag or between two layers of fine filter floss in any kind of flow-through filter or filter chamber so that the water is directed through it diffusely. PhosBan is best used in an up-flow filter such as the PhosBan Reactor, but the flow must be reduced sufficiently to prevent the granules from tumbling, which would grind them into powder.

Recommended Usage:

50 g per 50 gal (200 l) saltwater, 50 g per 100 gal freshwater. PhosBan is safe and can be used at more than 5 times the recommended usage quantity, but at high dosages, it can cause a drop in alkalinity. Monitor alkalinity and correct if necessary with buffer or other alkalinity supplements. The useful life of PhosBan depends on the phosphate concentration in the aquarium. PhosBan can be effective for up to several months before it needs to be changed. Replace PhosBan when phosphate levels begin to rise.


Synthetic ferrous oxide hydroxide.


Keep PhosBan in a tightly closed container. It has a shelf life of at least 3 years when maintained in a tightly closed container.

General Information:

PhosBan is a synthetic ferric oxide hydroxide in a granular form ideally suited for use in aquarium filters. PhosBan's porous structure has a high-surface area with many adsorption sites to bind large quantities of phosphate. PhosBan also adsorbs silicate, arsenic, and water-staining organic compounds. Neither phosphate nor any other substances are released back into the water, even after full saturation. PhosBan is safe to use continuously in freshwater and saltwater aquariums and ponds. To avoid problems that occur because of phosphate accumulation, keep the concentration of phosphate below 0.015 ppm as P. This target is achieved easily by using PhosBan on a permanent basis. Use PhosBan immediately when setting up a new aquarium to ensure that PO4 concentrations never rise in the first place. With PhosBan, large fish populations can be maintained without PO4 accumulation. In reef aquariums, PhosBan maintains the low phosphate levels needed to promote rapid growth in hard and soft corals.


Avoid contact with skin, eyes, and clothing, Do NOT take internally. Keep away from food. Do NOT breathe dust. Use a dust mask when handling. In case of contact, wash skin with soap and plenty of water, For contact with eyes, flush with plenty of water and seek medical attention. For aquarium use only. Keep out of reach of children.
