Instructions

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.

NOTE: To prepare small quantities, use 1/2 cup of Reef Crystals per each U.S. gallon of water. Mix as directed.

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.

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.

Adjust salt level accordingly. If specific gravity is too low, add more Reef Crystals. lf too high, add more dechlorinated water. 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.
