Barium?

[Randy Holmes-Farley Verified Community Expert]

My test came back with elevated levels of Barium (37.96 ug/L). I have not been intentionally dosing it. Should I be concerned?

That does not seem very high to me. I'd ignore it.

Oceamo shows that barium can come especially from zeolites, and to some extent from GAC.

You're welcome.

Happy reefing :)

Let barium hit 1 or 2 ug/l and see what happens to acros. Pale pale and dying. :(

My have gone down since this discussion. It's now at 4.27 ug/l

I don’t believe that is true. What is the evidence of that claim?

According to the Royal Society of Chemistry, barium has no known biological role. I seriously doubt that even zero barium will hurt corals.
