Product Description

Granular Ferric Oxide can stimulate excessive growth of undesirable algae in aquariums. High amounts of phosphorus levels are created by tap water, fish food and carbon the ferric oxide maintains the phosphorus levels under control and it absorbs the phosphorus in aquariums without leaching any iron ions in the tanks. It is a great way to reduce algae from growing in tanks.


Rinse before use

Use 1/4 to 1/2 cup per 190 litres for saltwater aquariums

Test phosphate levels and replace media when levels begin to rise (approx 1-3 months)

Alkalinity levels may drop when using ferric oxide be sure to monitor and adjust as needed
