Each grain is coated in real ocean water, providing natural balance and up to 100 times more beneficial bacteria than other sands. This sand encourages coral growth, discourages nuisance algae, and is naturally rich in strontium (7,000+ ppm) to support vibrant, healthy corals. Free of silica, it’s safe for all reef systems and promotes immediate biological activity while helping maintain stable water quality.
