This product is USELEsS to me
This product is USELEsS to me. It is 1 packet that cannot be opened. You need to make whole 20 gallon batch at once. And store it. It will go bad and lose its ability. I need small batches. Want RETURN and rREPLaCE with useable product. This 1 packet concept is NOT in advertisement. Unfair to consumer.
