Source for sulfur

[Harpo]

Where is everyone getting their sulfur from?

I am a bit confused. Are you looking for a sulfur supplement? Sulfur denitrifying media? Are you wondering where the sulfur in seawater comes from? Are you wondering why ICP tests often show elevated Sulfur?

I was looking for Sulphur for a Sulphur de nitrator.

Is the stuff they sell (Amazon) for fertilizer the same as we can use in the Denitrators?
