Tropic Marin Reef Salt 10kg is a high-quality, lab-grade aquarium salt specifically formulated for modern reef aquariums. Unlike standard marine salts, Reef Salt is designed with the unique needs of corals, invertebrates, and sensitive reef fish in mind, providing all the essential minerals and trace elements they require to thrive. Its carefully balanced composition closely replicates natural seawater, creating a stable and healthy marine environment right in your home. This premium reef salt contains appropriate levels of calcium, magnesium, potassium, and other tropical seawater trace elements that are vital for coral growth and overall reef health. By using Tropic Marin Reef Salt for regular water changes, aquarists can naturally replenish these elements, helping maintain stable pH and alkalinity while reducing the need for additional dosing. The salt also supports key water parameters: KH 7–8° dH, Ca 420–440 mg/l, Mg 1300–1400 mg/l, and K 400–420 mg/l, ensuring optimal conditions for reef ecosystems. Tropic Marin Reef Salt dissolves quickly and completely, producing clear, ready-to-use saltwater with a recommended specific gravity of 1.025–1.027 at 25°C (77°F) for typical reef systems. It is suitable for establishing new aquariums, performing regular water changes, or re-balancing pH in established tanks. A weekly partial water change of around 10% of the aquarium volume is recommended to maintain water quality and provide a steady supply of trace elements. Trusted by professional aquarists, public aquariums, and reef enthusiasts worldwide, Tropic Marin Reef Salt 10kg ensures consistency, reliability, and professional-grade results. Its reef-specific formula makes it the ideal choice for anyone looking to create a thriving, vibrant marine environment, from delicate corals to colorful reef fish. Tropic Marin Reef Salt 10kg is phosphate and nitrate free. Directions for use To achieve a salinity level of 32-35 ppt dissolve 35ml (approx. 37-40g) of the sea salt for every litre of water in a container, circulating continuously. The resulting seawater is ready for use as soon as the salt is completely dissolved. The specific gravity of the sea salt solution should be 1. 025 to 1. 027 at a temperature of 25-degree Celsius. A weekly, partial water change, replacing 10% of the total water volume with saltwater will help to maintain the water quality that your livestock needs for good health. Contains all tropical sea water trace elements.
