What is it?[edit]
Salinity is the saltiness or dissolved salt content of a body of water. It is a general term used to describe the levels of different salts such as sodium chloride, magnesium and calcium sulphates and bicarbonates.
It is typically expressed in the unit - parts per thousand (ppt) or approximately grams per litre. To measure this accurately in an aquarium you need to use a hydrometer or refractometer.
Specific gravity at 25°C (77°F) | salinity (ppt) |
1.018 | 26.9 |
1.019 | 27.8 |
1.020 | 28.7 |
1.021 | 30.6 |
1.022 | 31.5 |
1.023 | 33.4 |
1.024 | 34.3 |
1.025 | 36.2 |
