Reef Macro

Liquid macro mineral supplement for reef and marine aquariums.

This balanced macro mineral blend supports the growth of corals, invertebrates, and shell-forming organisms. It contains calcium, magnesium, potassium, and strontium in proportions similar to natural aragonite. When used together with Crystalpro Reef Micro and kH Plus, it provides the essential minerals required in seawater for coral tissue, skeletal development, and color enhancement.
