So, you have decided to set up a saltwater tank? Congratulations! Saltwater tanks are a lot of work, and mixing salt water will be a major part of your life now. While it may seem simple, mixing saltwater is an art. If the salinity levels are too low or too high, your fish will become stressed and, in extreme cases, die. That is why measuring salinity is a vital part of owning a saltwater tank. The best tool for this is a Refractometer. If this is your first time hearing about Refractometers, don’t panic!

Refractometer is a tool that accurately measures the salinity of your aquarium. Those of you who paid attention in school might recall your science teacher talking about the refraction of light. If you didn’t pay attention in class like many of us or just can’t remember – here is a simple refresher. Light travels in a straight line. But when it shines through a medium like glass or water, it changes direction or bends. Just how much the light bends is determined by the medium that the light shines through. This bending of the light is referred to as refraction. And, it turns out that you can use refraction to determine the salinity of your aquarium. You see, light refracts differently according to the amount of salt that is dissolved in the water. A Refractometer can read these differences, allowing you to accurately measure the salinity of your tank.
