Instant Ocean Aquarium Hydrometer The Instant Ocean Aquarium Hydrometer is a very accurate, reliable watertest equipment that is easy and simple to operate. This Instant Ocean Hydrometer delivers precise full-range salinity and specific gravity readings. Features: · Accurate functioning · Easy-to-use swing-arm style hydrometer for brackish and marine systems · Precise full range salinity and specific gravity readings · Large easy-to-read pointer and wide stabilizer base · No-wet-hands-design · Ideal for use in water temperatures from 68° to 85°F Item Specifications: Parameter Suggested Level: Suggested Level: Average Level: Reef Aquarium FOWLR Aquarium Coral Reefs Specific Gravity 1.023 - 1.025 1.020 - 1.025 1.025 Temperature 72 - 78°F 72 - 78°F 82°F pH 8.1 - 8.4 8.1 - 8.4 8.0 - 8.5 Alkalinity 8 - 12 dKH 8 - 12 dKH 6 - 8 dKH Ammonia (NH3) Undetectable Undetectable Near Zero Nitrite (NO2) Undetectable Undetectable Near Zero Nitrate - Nitrogen (NO3) < 1.0 ppm < 30 ppm 0.25 ppm Phosphate (PO4) < 0.2 ppm < 1.0 ppm 0.13 ppm Calcium 350 - 450 ppm 350 - 450 ppm 380 - 420 ppm Magnesium 1250 - 1350 ppm 1150 - 1350 ppm 1300 ppm Iodine 0.06 - 0.10 ppm 0.04 - 0.10 ppm 0.06 ppm Strontium 8 - 14 ppm 4 - 10 ppm 8 - 10 ppm Installation: · Rinse hydrometer with fresh water before using · Slowly fill hydrometer 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 · Periodic cleaning is recommended to remove deposits that can accumulate on pointer, causing inaccurate readings · To clean, soak hydrometer in mild acid (vinegar) for 30 minutes, then rinse
