Copper is a trace element present in small quantities in the seawater of reefs all around the world.

​

Copper is an essential trace element that kept in small concentrations has positive impacts on coral skeleton calcification, health and colouration along being needed for multiple biological processes of corals and other organisms.

​

It is important to check Copper levels through ICP analysis and ensure adequate levels and stability by dosing a Copper supplement as needed.

​

Naturally, Copper in seawater varies but its concentration doesn't go above 3 µg/l.

​

Copper used in conjunction with a regular testing procedure, allows any reefer to make corrections to Copper levels ensuring the levels in their tank water stay within the best range for their friends.

​

1 ml of Reef Zlements Copper increases the Copper concentration of 100 litres of water by 2 μg/l.
