JUWEL Phorax is an extremely effective filter medium for the breakdown of phosphates in your aquarium. It effectively reduces algae growth and can contribute significantly to improved plant growth.
Phosphates regularly enter the aquarium via the fish food and are hardly broken down naturally. However, plants need very little phosphate for their natural growth (fresh water: 0.05 mg/l, salt water 0.01 mg/l). In certain circumstances, too much phosphate can cause an algae infestation.
Phorax consists of an aluminum mineral, which binds the released phosphate by forming a non-water-soluble aluminum phosphate and thus removes it from the water. This makes JUWEL Phorax extremely effective and binds up to 12 mg of phosphate per gram of Phorax.

Features of JUWEL Phorax:
• Reduces phosphate
• Inhibits algae growth
