Two Little Fishies PhosBan Phosphate Adsorption Media - 454g
Overview Highly porous and super absorbent, Phosban helps clear up aquarium phosphate problems in no time - knocking out nuisance algae in the process. Granular structure is derived from ferric oxide hydroxide for maximum effectiveness. PhosBan provides durable protection: keeping phosphate levels manageable for months after application. Also absorbs organic compounds and other pollutants for a superior clean.
Instructions This product can be rinsed briefly before use, but since it is friable, do not stir the granules, which would pulverize them. It is best used without a media bag in an upflow filter, such as the PhosBan Reactor, and the flow must be reduced sufficiently to prevent the granules from tumbling, which would grind them into powder. An alternative is to put product in a tightly-packed media bag or between 2 layers of fine filter floss in any kind of flow-through filter or filter chamber so that the water is directed through it diffusely.
It is recommended to use 50g per 50 gallon of saltwater and 50g per 100 gallons of freshwater. Replace PhosBan when phosphate levels begin to rise.
