Following a fertiliser explosion at Highlands Farm on 24 July 2026, Coral Passion has stopped trading from the site. Our insurance claim with MSIG Europe is still ongoing, but despite our efforts it does not look promising, and the future of the business is uncertain. Thank you to everyone who has supported us. I am still available & working on aquarium installations and maintenance. For more information, please contact tony@coralpassion.co.uk.

What is this Trace Elements Barium from Reef Zlements?

This Trace Elements Barium is part of an extensive range of marine additives from industry experts Reef Zlements. It's an easy-to-dose supplement and designed to support your corals during the all-important calcification process.

How do I use this Trace Elements Barium?

It's important to first check your reef tank's barium levels prior to any dosing. This is best done with a professional ICP test. These tests will not only tell you whether your barium levels need adjusting, but your levels of other trace elements too.

To dose, add 1ml of barium per 100L of saltwater. This will increase barium levels by 1 µg/l. Its widely accepted that 10 µg/l is an optimum concentration level for a reef tank. Avoid dosing all at once as high doses of barium can be toxic for marine animals.

What is barium and why is it important for my reef tank?

Barium is a trace element present in coral reefs across the world. It plays an important role in coral growth and serves to control calcification within a coral's skeleton. It's present in other product that you may add to your aquarium too, including activated carbon, salt mixtures, cements, and food.
