The Instant Ocean Testing Hydrometer for Aquariums makes the difficult task of reaching the correct salt level in your marine aquarium much easier. Maintaining the right level is vital to creating and maintaining a thriving marine environment. It’s important to make sure that synthetic sea salt is mixed in the proper ratio to mimic natural sea water. The Instant Ocean Testing Hydrometer is a precise, reliable tool that provides full-range salinity and specific gravity readings, and it’s accurate to ± 0.001. It’s simple to use and read with a clearly marked safe zone.

Hands stay dry when filling while testing aquarium salt level and specific gravity
Before use, condition hydrometer by soaking it in saltwater for 24 hours.
Slowly fill the Instant Ocean Hydrometer by dipping bottom corner fill port below water surface until water flows up and over inner weir.
Dislodge air bubbles by gently tapping hydrometer or pointer. Air bubbles on the pointer may result in inaccurate results.
Place the hydrometer on a level surface and read specific gravity (inside scale) and salinity (outside scale).
Rinse thoroughly in freshwater after each use to prevent mineral/salt buildup which can affect accuracy. Salt and calcium deposits that accumulate on the pointer will result in incorrect results. If crystallization occurs inside the unit, soak in lukewarm water or vinegar for 30-minutes, rinse with freshwater and air dry.
