Does anyone know of something you can test your hydrometer with? Say like a common food liquid that has a specific gravity? The problem i just ran into was salinity levels way off the chart. I was pluging along with my tank for the last year and a half, assuming(my first mistake) that my hydrometer was correct. the only reason I questioned it was when i was making water for my last water change i forgot how much salt i had put in the bucket. So after i mixed it I floated my hydrometer and it read low. No matter how much salt i added it didn't change. So there I stopped. Today was the first day I could get to the LFS and I got myself a new hydrometer. I decided to buy the style you fill and it has a little pointer inside. I got it home and tested my tank and it had to be close to Dead Sea levels because it was so high it pegged the needle full at the top, past 1.032 sg. So out came the bucket and i did a little water change and brought the salinity down to 1.024 sg. I'm a little ashamed of myself and feel like slapping my own hand. So what I want to find is something that has a set specific gravity so I can test my hydrometer until I can afford a refractometer.
