Keep a healthy underwater environment with Instant Ocean Reef Salt for Aquariums. It contains essential ocean reef elements in concentrations greater than those found in natural seawater with extra calcium to encourage the growth of large and small polyp stony corals as well as coralline algae. This salt provides vital nutrients and extra vitamins help to promote vigorous growth and survival of corals, anemones and other invertebrates. It also neutralizes traces of heavy metals often present in tap water. Maintain your aquarium and watch it flourish with Instant Ocean Reef Salt.

HAZARDS TO HUMANS: Reef Crystals 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) with cool water and seek medical attention.
Recommended Specific Gravity Range: 1.020-1.026 at 77°F. NOTE: 1.4 lbs of Reef Crystals is formulated to create 5 gallons of saltwater at a specific gravity of 1.021.
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.
Always add the salt mix to the water, not the other way around. Adding water to the salt mix briefly creates a highly concentrated solution that can lead to precipitation of some ingredients. Always allow newly mixed salt water to circulate with a powerhead or airstone at least overnight before use. This allows the carbon dioxide in the aquarium water to reach equilibrium with the carbon dioxide in the atmosphere, which normalizes pH. It also adds oxygen.
Instant Ocean® is formulated to provide a solution with levels of calcium and magnesium found in natural seawater (NSW), assuming you use purified water to dissolve the sea salt. Tap water most often contains dissolved calcium, magnesium and other minerals that will add to the levels provided by Instant Ocean®. The specific gravity of NSW is typically 1.026 (35 parts per thousand, or ppt, salinity). When dissolved in pure water to a specific gravity of 1.026, Instant Ocean® should provide a solution that has 400 mg/L calcium ion and 1320 mg/L magnesium ion. If Instant Ocean® is dissolved to a lower specific gravity, then these concentrations (and, in fact, the concentration of every other ion) will be proportionately lower.
The most common cause of poor solubility is moisture. Some of the compounds used in sea salts are hygroscopic, meaning they readily and quickly draw moisture from their surroundings. If your sea salt has any “clumps” or hardened sections, then this is a sure sign that moisture has been introduced. Sea salt that has absorbed moisture may dissolve with the addition of aeration. The best way to avoid moisture in your sea salt is to re-seal the container immediately after use.
Instant Ocean® has never contained a dechlorinator or any type of chelator. It is advisable to dechlorinate using a commercially available de-chlorinator when using tap water to dissolve Instant Ocean®.
Instant Ocean® is engineered to closely match natural seawater, and Reef Crystals® is enriched to facilitate the growth of corals and other invertebrates in a reef aquarium.

Instant Ocean is the only brand that came to mind when I decided to start a saltwater tank!
Awesome product. Used to be a great price at Chewy, but it looks like price went up everywhere.
