We recommend running 35 ppt, which would be 1.0264 sg at 77F.

NOTE: The specific gravity is temperature dependent. With increasing temperature the specific gravity decreases. Therefore, the measured water temperature should be 25 °C / 77 °F to obtain a correct result.For an exact, reliable measure of the specific gravity, we recommend to use the Tropic Marin® High Precision Hydrometer.

• Fill the measuring cylinder with maximum 400 ml saltwater (water temperature = 25 ° C / 77 °F). We recommend a 250 mL cylinder that is ~1/2 full.
• The hydrometer should be dry and clean.
• Gently place the hydrometer into the water until it floats freely.
• Now read the specific gravity on the blue part of the scale of the hydrometer at the bottom of the meniscus - NOT at the level of the  water (which may be creeping up towards the edges!)
• To avoid any distortion of future measurements, rinse the measuring cylinder well with fresh tap or reverse osmosis water to remove salt residues after each use.
