Barium is a trace element present in reefs all around the world and plays a strong role in coral calcification. 

​

It is important to check its levels through ICP analysis and ensure adequate levels and stability by dosing Barium as needed.

​

Barium in seawater varies widely between oceans and depth but, it is agreed that a 10 µg/l level is an acceptable concentration level.

​

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

​

​1 ml of Barium Zlement increases the Barium concentration of 100 litres by 1 μg/l.
