Phorax

Phorax

JUWEL Phorax is a highly effective filter medium used to break down phosphates in your aquarium. This effectively reduces the growth of algae and can contribute to improved plant growth.

Phosphate regularly enters aquariums through fish food and is naturally very unlikely to be broken down. However, plants only need small amounts of phosphate for their natural growth (freshwater: 0.05 mg/l, saltwater 0.01 mg/l). Too much phosphate can in some cases trigger excessive 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. This makes JUWEL Phorax highly effective and binds up to 12 mg phosphate per gram of Phorax.
