We tested every single hydrometer on the market and this one is by far the most accurate and easy to use. We still prefer a refractometer but more a cost effective option that we stand behind, go with this aquarium salinity hydrometer.
Key Features

- Large easy to read scale
- Precise within +/- 1.0 SG

Instructions:
Before using this salinity aquarium hydrometer being by soaking it in saltwater for 24 hours.
Step 1 – Slowly fill the Hydrometer by dipping bottom corner fill port below water surface until water flows up and over inner weir.
Step 2 – Dislodge air bubbles by gently tapping hydrometer or pointer. Air bubbles on the pointer may result in inaccurate results.
Step 3 – Place the hydrometer on a level surface and read specific gravity (inside scale) and salinity (outside scale).
Care:
Rinse thoroughly in freshwater after each use to prevent mineral/salt buildup which can affect accuracy.
Reef casa recommends keeping your salinity range from 1.024-1.026 ppt
