ESV's Calcium Chloride is a very pure anhydrous
grade free of phosphates and nitrates. The advantage
of using Calcium Chloride as a calcium supplement
in marine aquaria is its very high solubility in water.
This property allows the aquarist to rapidly adjust
calcium concentrations to desired levels. The aquarist
should be aware that Calcium Chloride does not add
bicarbonate and carbonate ions to the system. Since
most calcifying organisms require these ions in
addition to calcium ions, the aquarist should monitor
the alkalinity frequently when using Calcium Chloride
and make the proper adjustments with a buffer additive.
