I dropped my old hydrometer and it disintegrated, so I bought another. I went to check it in my cities tap water, at 75 degrees, and it is reading 0.998 - 0.997. That is way off from the 1.000 standard it's supposed to sit at.
Is this Normal? It maybe the water, it is EXTREMELY hard and almost undrinkable. I'm going to the grocer's in a few minutes and I'm going to buy some water that I would normally use in my mead to cross check the readings, but it still seems real fishy.
Any similar experiences? Thoughts?
