Marine Salt and Saltwater

High-quality marine salt is essential for maintaining the ideal salinity in reef tanks, marine aquariums, and fish-only systems. Proper salt blends provide the essential minerals and trace elements that help corals, live rock, and tropical fish thrive, supporting both growth and overall aquarium health. At GardenSite, the marine salt range includes a variety of brands and sizes, from compact sachets to large bags, making it easy to mix the perfect salinity for even the smallest volumes.
