Why does BRS recommend this?

The Red Sea line of additives is one of our most popular lines.  Red Sea has done testing to see what elements corals take up in what ratios. They then developed an entire system to keep your reef tank from being depleted of any single element, while giving your corals great health and vibrant coloration.  

Provides the 31 minor and trace elements required by corals in 4 - 100 mL bottles.
