Without measuring the initial pH and the end pH, you have no idea what you are actually doing to the water. If you have really hard water that may not much of a difference.By a few drops, I mean about 2 tablespoons, but I'm not measuring, it takes about a month to go through an entire bottle if you use it consistently every day.
By saying you are only adding a few drops when you are adding 2 tablespoons, you are misleading people about what you are doing. There is a huge difference between a drop and a tablespoon.
