Marine Salt’s™ enhanced alkalinity ensures a more stable pH than competing salt blends. Marine Salt™ possesses excellent solubility characteristics and will provide a clear, ready to use solution in only a few minutes. Marine Salt™ is a convenient and easy to use one-part formula that is ideal for mixing either small or large batches of saltwater. Utilizing state of the art production facilities ensures a consistent and uniform particle size that will not separate in packaging or shipping and will provide a consistent saltwater mix every time. For Reef environments, use Seachem Reef Salt™ instead. It is specifically designed to meet the requirements of a reef system. 1. Mix Marine Salt™ with dechlorinated tap or purified water. We recommend the use of a commercial dechlorinator like Prime® to neutralize any tap water chlorine and/or chloramines. If source water quality is extremely poor we recommend purification with a Seachem Pinnacle™ RO/DI system. NOTE: To prepare small quantities, use 34 g of Marine Salt™ per each liter (1/2 cup per each US gallon) of water. 2. Stir well to ensure a good mix. Although the Marine Salt™ solution may be used immediately, we suggest aerating the water until it achieves oxygen/carbon dioxide equilibrium. 3. Measure specific gravity. Recommended range is 1.020 – 1.023 at 24 C (75 F). NOTE: 675 g of Marine Salt™ is formulated to create 20 liters (1.4 lbs per 5 US gallons) of saltwater at a specific gravity of 1.021. 4. Adjust salt level accordingly. If specific gravity is too low, add more Marine Salt™. If too high, add more dechlorinated or purified water. 5. Change 25% of aquarium water every 2-4 weeks (or as necessary) to maintain optimum water quality.
