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 gets into aquariums through fish food and are naturally very unlikely to be broken down. However, plants need only tiny quantities of phosphate for their natural growth (fresh water: 0.05 mg/l, saltwater 0.01 mg/l). Too much phosphate can, in some cases, 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. This makes JUWEL Phorax highly effective, binding up to 12 mg of phosphate per gram of Phorax.

Characteristics of JUWEL Phorax:
• Reduces phosphate
• Slows down algae growth
• Promotes plant growth
• Suitable for use in freshwater and saltwater aquariums

Juwel Phorax has been developed for the effective removal of phosphates in both fresh and saltwater.

This product makes adding a phosphate remover to your Juwel aquarium easy. Simply remove the upper blue sponge and replace with Phorax.

In our experience even low levels of phosphate cause unwanted algae growth and slow coral growth.

Juwel advise replacing Phorax at every water change, but stocking levels and maintenance regimes vary. Instead we recommend using a phosphate test kit and replace Phorax once phosphate levels start to rise
