salinity™ is a blend of salts specifically formulated for the reef aquarium that contains all essential major, minor, and trace components found in natural reef waters, but contains no toxic or non-essential components. Additionally, salinity™ is the most concentrated salt blend on the market. With a hydration level of <0.5% salinity™ will yield a greater volume of prepared saltwater at a salinity of 35‰ per unit of weight than any other salt mix currently on the market.
salinity™ is identical to the distribution of anions and cations found in Natural Sea Water (NSW). We have compiled data from all the oceans and seas on the Earth, and have targeted the midpoint of the range for each element. We guarantee to be within ± 5% of the midpoint.
At a salinity of 35‰, for calcium, magnesium, strontium, pH, and alkalinity we have the following targets and/or ranges (see below).
S = [0.3348 * T] + [1325 * H] - 1330.4525 (calibrated at 15.56 °C (60 °F))
S = [0.2211 * T] + [1325 * H] - 1330.4525 (calibrated at 25 °C (77 °F))
where S is the salinity in parts per thousand; T is temperature in degrees centigrade (range of 13-30 °C); and H is the uncorrected hydrometer reading. If you don't mind an error on the order of ±3%, simply use the following table:
| If the water temperature is: | cal.@ 15.56 °C | cal.@ 25 °C | |
|---|---|---|---|
| degrees C | degrees F | then target H= | then target H= |
| 13 - 15 | 55 - 59 | 1.027 | 1.029 |
| 16 - 19 | 60 - 66 | 1.026 | 1.028 |
| 20 - 23 | 67 - 73 | 1.025 | 1.027 |
| 24 - 27 | 74 - 81 | 1.024 | 1.026 |
| 28 - 30 | 82 - 86 | 1.023 | 1.025 |
USAGE NOTE: NEVER mix salt in an aquarium containing livestock. Transfer livestock to the aquarium AFTER salt is completely mixed and specific gravity has been adjusted. Use Seachem's Stability® to avoid "new tank syndrome" and to prevent unnecessary livestock losses in a new system.
