Nexus is a superior lanthanum chloride phosphate remover that initiates a bond between calcium and phosphate to instantly trap and lock away phosphate.

On impact Nexus will create a foggy appearance; this is the reaction of the phosphates being locked away.

This will clear in approximately 20 minutes.

Once phosphate has been locked away it will remain insoluble until removed by mechanical filtration.

Nexus offers you a quick, simple and unique way to remove phosphates instantly without the need for any additional reactors or equipment.

Nexus is completely reef safe and will not harm inverts, corals or any aquatic life.
