Seachem Reef Calcium – 500 Ml

Reef Calcium is a concentrated (50,000 mg/l) bio-available polygluconate complexed calcium intended to maintain calcium in the reef aquarium without altering pH (formulated at pH 8.2). Polygluconate complexation confers several benefits: it increases the bio-availability of the calcium, it provides a rich source of metabolic energy to help maintain peak coral growth, and it inhibits calcium precipitation/alkalinity depletion. One side benefit includes enhancement of denitrification. Polygluconate contains no nitrogen or phosphorous, thus it is biologically impossible for it to lead to algae growth in a properly maintained reef system. Reef calcium is intended to maintain calcium levels; if calcium becomes seriously depleted one should either perform a water change or use an ionic calcium supplement to restore the depleted level of calcium.
