Why does CORAL FARM  recommend this?

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