After dissolving Instant Ocean® in purified water, my calcium and/or magnesium concentration seems lower than expected.

This allows the carbon dioxide in the aquarium water to reach equilibrium with the carbon dioxide in the atmosphere, which normalizes pH. Always allow newly mixed salt water to circulate with a powerhead or airstone at least overnight before use. Adding water to the salt mix briefly creates a highly concentrated solution that can lead to precipitation of some ingredients. What is the proper way to mix salt water?Īlways add the salt mix to the water, not the other way around. Transfer animals to the aquarium AFTER salt is completely mixed and aerated and specific gravity has been adjusted. USAGE NOTE: NEVER mix salt in an aquarium containing animals. Change 20% of aquarium water every two weeks to maintain optimum water quality.lf too high, add more dechlorinated water. If specific gravity is too low, add more Instant Ocean. NOTE: 1.5 lbs of Instant Ocean is formulated to create 5 gallons of saltwater at a specific gravity of 1.022. Recommended Specific Gravity Range: 1.020 - 1.024 at 77☏. Measure specific gravity with an Instant Ocean® Hydrometer.Although the Instant Ocean solution may be used immediately, we suggest aerating the water until it achieves oxygen/carbon dioxide equilibrium. NOTE: To prepare small quantities, use 1/2 cup of Instant Ocean per each U.S. Mix Instant Ocean® with ordinary dechlorinated tap or purified water.
