Fritz PRO Bulk Calcium Chloride Professional Aquarium Supplement

Fritz ProAquatics Calcium Chloride Anhydrous can be used alone or as part of a two part calcium & alkalinity supplement system to raise calcium levels in enclosed reef systems. Monitoring and maintaining calcium levels is an important part of helping to stabilize water chemistry values, resulting in better coral, coralline algae and invertebrate growth and health.

1 gram per 10 gallons will raise calcium level  approx. 10 ppm. One teaspoon (approx. 5.2 g) per 10 gallons will raise calcium 50 ppm. Dissolve appropriate amount of calcium chloride in RO/DI or distilled water. It is recommended to dose in partial increments of 1/3 to 1/2 of the total. Wait 24 hours after first partial dose, check calcium levels, dose another portion.

NOTE: Due to the variation of granular size, conversion between volume and weight of powdered products are approximate; as a precaution, dose less than the calculated amount and measure the effect before adding the total amount.
