Provides temporary alkalinity and helps maintain pH within the desired range when used as directed. Adds no conservative elements, such as chloride, to the aquarium. Improves upon the industrystandard powdered calcium supplement over the past three decades. Contains 54.2% (520,000 ppm) calcium by dry weight.

Formulated by a marine scientist.
