Seachem Reef Calcium 250ml is a concentrated (50,000 mg/L) bioavailable polygluconate calcium complex, intended to maintain calcium in reef aquariums without altering the pH.
It contains no nitrogen or phosphorus, making it biologically impossible to promote algae growth in a properly maintained reef system.
It can be used alone to maintain calcium but will provide enhanced coral growth rates when used in conjunction with an ionic calcium supplement.
It is intended for the maintenance of calcium levels. If calcium becomes sufficiently depleted, you should either perform a water change or use an ionic calcium supplement to restore the depleted calcium level.
