Instant Ocean® Sea Salt is the most carefully formulated and universally preferred sea salt in the world. It's why our Sea Salt is used exclusively by many of the leading large-scale aquariums and research facilities across the country.

No matter what size your aquarium, science-based Instant Ocean products offer the smartest, easiest way to bring the ocean home. We invite you to explore our website and get inspired!

1. Mix Instant Ocean® with ordinary dechlorinated tap or purified water.
NOTE: To prepare small quantities, use 1/2 cup of Instant Ocean per each U.S. gallon of water. Mix as directed.

2. Stir vigorously to ensure a good mix. Although the Instant Ocean solution may be used immediately, we suggest aerating the water until it achieves oxygen/carbon dioxide equilibrium.

3. Measure specific gravity with an Instant Ocean® Hydrometer. 

Recommended Specific Gravity Range: 1.020 - 1.024 at 77°F.
NOTE: 1.5 lbs of Instant Ocean is formulated to create 5 gallons of saltwater at a specific gravity of 1.022.

4. Adjust salt level accordingly. If specific gravity is too low, add more Instant Ocean. lf too high, add more dechlorinated water.
5. Change 20% of aquarium water every two weeks to maintain optimum water quality.

USAGE NOTE: NEVER mix salt in an aquarium containing animals.

In New Aquariums:
Transfer animals to the aquarium AFTER salt is completely mixed and aerated and specific gravity has been adjusted.

CAUTION: INSTANT OCEAN IS NOT FOR HUMAN CONSUMPTION. KEEP OUT OF REACH OF CHILDREN.
Contact in dry form may cause skin or eye irritation.
In case of contact, completely flush skin or eye(s)
