Bleach solution

35 g Copper Sulfate
5 g Sodium Bisulfate
100 g Potassium Bromide
One litre water


Bleaching time: One and a half times the time it takes to clear.

Temperature:  20C            Agitation:  Intermittent

More or less the same as the original Jeff Blyth's original Copper Sulfate Bleach, again subbing a dry powder to save on hazardous shipping charges of liquid acetic acid.

Shelf life: Pleasant blue-green color when mixed, dirty green when exhausted. Not prone to oxidation like PBQ.
