Salinity is the level of salt within your aquarium.
*PPT = Parts Per Thousandth*
The average marine aquarium will require a consistent salt level of between 1.024 and 1.026ppt.
This can be measured through the use of a refractometer. The first and most important step would be to calibrate your refractometer at 0 by using RO.DI (Reverse Osmosis De-Ionised) water. This will calibrate the level at 0. This will ascertain an accurate reading.
You would then, using a pipette, sprinkle (or lightly dip) saltwater to cover the lens of the refractometer, closing the cover and pointing the refractometer onto a white source of light.
Looking through the eye-piece, you would peer into the refractometer, where you would see the contrast line (blue vs white). This would tell you what salt level of your aquarium is.
