Juwel Phorax is a very effective filter medium used to break down phosphates in aquariums. The benefit of breaking down phosphates is a reduction in algae growth and, often an improvement in the growth of aquarium plants.

Phosphates arrive in aquariums via fish food and are very unlikely to be broken down naturally. Plants only need tiny quantities of phosphate for their natural growth (fresh water: 0.05 mg/l, saltwater 0.01 mg/l). Too much phosphate can trigger prolific algae growth.

Phorax consists of an aluminium mineral which binds dissolved phosphate by creating a water-insoluble aluminium phosphate and removing it from the water. Juwel Phorax binds up to 12 mg of phosphate per gram of Phorax.

Juwel Phorax is suitable for use in both freshwater and saltwater aquariums.
