Instant Ocean Hydrometer
Discover your aquarium's correct salt content and specific gravity reading every time with the Instant Ocean Hydrometer. Features an easy-to-read, two-color full range scale with safe zone, extra-wide stabilizer base and accuracy to + /- 0.0001! Keep your hands dry and your fish safe with this handy device!
Instructions: Rinse hydrometer with fresh water before using. Slowly fill it by dipping bottom corner fill port below water surface until water flows up and over inner weir. Dislodge air bubbles by tapping hydrometer or pointer, gently with pencil. Placing hydrometer on a level surface, read specific gravity (inside scale) and salinity (outside scale). For most marine aquariums, recommended specific gravity is 1.020 to 1.024. Rinse hydrometer with fresh water before storing. Periodic cleaning is recommended to remove deposits that can accumulate on pointer, causing inaccurate readings. Soak hydrometer in mild acid (vinegar) for 30 minutes, then rinse.
