As it says, my Seachem Water Conditioner is smelling TERRIBLE. Like sulphur, but a sharper smell than sulphur. I honestly don't know how to describe it. Does it affect the fish?
The active ingredient (part) of most water conditioners that neutralizes chlorine/chloramine is sodium thiosulfate (a sulphur based compound).
If it didn't smell like that, it wouldn't work.
Some bottles of prime, or after a certain period of time, give off an extreme smell of sulfur. Worried me too at first but it’s fine and still effective per seachem
