Reef Calcium is a concentrated (50,000 mg/L) bioavailable polygluconate complexed calcium intended to maintain calcium in the reef aquarium without altering pH. Polygluconate complexation confers several benefits: it increases the bioavailability of the calcium, it provides a rich source of metabolic energy to help maintain peak coral growth, and it prevents calcium precipitation/alkalinity depletion. Polygluconate contains no nitrogen or phosphorous, thus it is biologically impossible for it to lead to algae growth in a properly maintained reef system. Guaranteed Analysis (Amounts per 1 g): Calcium (min) 50 mg, Calcium (max) 52 mg, Ingredients: calcium gluconate
DIRECTIONS: Add 1 capful (5 mL) per 80 L (20 gallons*) twice a week. You can increase the dose or frequency based on growth response but do not exceed 3 capfuls per 80 L (20 gallons*) per day. Each dose will raise calcium by about 3 mg/L. HINTS: Use the Reef Status: Calcium test kit to measure calcium. It is not necessary to exceed 380 mg/L total calcium when using this product. Color and clarity may vary between lots.
