Vinegar is 5% acidity Glacial Acetic Acid is 28% (GAA) You could just use 5 times more vinegar as GAA..... or, to 1 gallon of water... add 2 oz of GAA or 10 ounces of Vinegar.... Use WHITE vinegar.... The purpose of the stop is to provide an acidic environment to stop the development prosess, that requires a alkaline environment.... Use of water just takes longer and does not stop as fast the development process.., as it dilutes the developer.... not changing the PH...
