Special Features
Water balance: Seachem Reef Reactor is a high-purity source of aragonite, which supplies all important elements for optimal ionic balance and robust coral growth and coloration in reef aquaria.
Grain Size : With a grain size of approximately 0.5-1 cm, Reef Reactor is intended for use in calcium reactors where it is slowly dissolved with the addition of carbon dioxide.
Support: As it dissolves, Reef Reactor provides calcium, magnesium, strontium, potassium, and carbonates among other important elements for reef aquaria
Stabilization Reef Reactor is excellent at increasing and stabilizing alkalinity, which also supports a stable pH and encourages the rapid formation of coral skeletal material.
