Contains two molecules of copper to attract sulphur, and is bound in the pores of high quality bentonite. The copper is applied to the bentonite making it insoluble, and as the bentonite is completely covered, it is completely inactive so that fining cannot occur.
The H2S / Mercaptan Remover will not impart a metallic taste like copper sulphate.
Settle for a couple of days then rack off. Blue fining is not required unless gross over addition of Hydrogen Sulphide remover is added.
