Reef Zlements Barium 1L offers a practical solution for maintaining stable barium levels in reef aquariums. As a trace element, barium supports coral calcification and is naturally found in reefs across the globe. Its concentration in seawater can fluctuate depending on location and depth, so supplementing barium accurately helps maintain the health and structure of coral systems.

Key Features:

• Supports healthy coral calcification
• Designed for use following ICP testing results
• Contributes to maintaining stable barium levels in reef tanks
• 1 ml of solution increases barium by 1 µg/l per 100 litres of water
• Recommended concentration: 10 µg/l in reef aquariums
• Simple to dose and monitor as part of a regular reef care routine
• Developed for use with the Reef Zlements system

Using Barium Zlement as part of a routine testing and dosing strategy helps reef keepers maintain optimum water conditions for coral growth. Reliable and easy to use, it’s a trusted addition for anyone managing a serious reef setup.
