Precision-engineered to recreate natural reef chemistry.

NeoMarine Salt by Brightwell Aquatics is one of the most meticulously crafted salt blends available—formulated by marine scientists, tested for years across complex reef systems, and manufactured in-house under tight quality control.

Key Features:

Lab-grade purity: Made with only USP- and ACS Reagent-grade materials—no evaporite, no anti-caking agents, no unnecessary additives like vitamins or amino acids.
Natural seawater replication: Delivers all major, minor, and trace elements in precise natural ratios. This includes anhydrous forms of magnesium, calcium, potassium, and strontium.
Consistent mix, every time: Homogeneous particle size ensures fast, even dissolving and easy handling—no settling or layering in the box.
Reef-tested performance: Proven in long-term coral and fish systems, including public aquariums and coral propagation labs. Repeated coral spawn events, vibrant coloration, and healthy growth across all reef inhabitants.
