Brightwell Aquatics Precision Salt Blend is a scientifically-formulated marine salt mix designed to closely replicate the natural seawater chemistry essential for healthy reef aquaria. Extensively tested and based on the latest marine biology and chemistry research, this blend supports optimal conditions for both fish and invertebrates.

Each batch is manufactured in-house to maintain consistent quality, with full lot control and sampling for quality assurance. The dry blend is processed to ensure uniform particle size, allowing for easier mixing and accurate salinity control. When mixed at 134 g per 3.785 L (1 US gallon) of purified water, it yields a specific gravity of approximately 1.025 g/cm³, a pH of around 8.30, and an alkalinity of about 7.5 dKH.
