Juwel Aquarium Filter material Phorax for Bioflow 6.0

Juwel Phorax is a highly efficient filter medium for the removal of phosphates in your aquarium. This removal effectively reduces algae growth and can contribute to improved plant growth. Phorax is made from an aluminum mineral that binds dissolved phosphate by forming an insoluble aluminum phosphate, thus removing it from the water. Juwel Phorax is highly effective and binds up to 12 mg of phosphate per gram of Phorax.
