SeaChem Reef Reactor Medium Grain .5-1cm 2L

Reef Reactor supplies all important elements for optimal ionic balance and robust coral growth and coloration in reef aquaria. It is intended for use in calcium reactors where it is dissolved slowly with the addition of CO2. As it dissolves, it provides calcium, magnesium, strontium, potassium, and carbonates among other important elements for reef aquaria. It is excellent at increasing and stabilizing alkalinity, which also supports a stable pH and encourages the rapid formation of coral skeletal material.
