Hi, Can a old Aluminium co2 cylinder/ converted dive tank give a bad taste ? ? Recently did a keg of soda water and after being away and not touching for about 3 week the water was undrinkable with what i can say with a metallic taste. Keg was throughly clean before and filled with filtered water and forced carbed . The keg also has black deposit on the bottom , or is this something else
