I crushed a campden tablet and dissolved it in a gallon of water. I used this solution to sanitize a 5 gallon carboy. i then poured the campden solution into a one gallon plastic jug to save for the next carboy. That was twoo weeks ago. Today I noticed a black mold growing on the top of the water. I am new to winemaking but I am sure this is not a good thing. What gives?
