Product Description Seachem Reef Complete 250Ml Ingredients Calcium Chloride, Magnesium Chloride, Strontium Chloride Directions Beginner Use 1 capful (5 mL) per 80 L (20 US gallons) twice a week. Check calcium every 2 weeks and adjust amount or frequency accordingly. Advanced Check calcium level (use Reef Status: Calcium to measure calcium), then follow addition regimen above until calcium is adjusted to 380–420 mg/L. Each 5 mL/80 L (20 US gallons) will raise calcium by about 10 mg/L. Quantity or frequency can be adjusted, but do not exceed 12.5 mL/80 L (20 US gallons) per day. Thereafter, use as required to maintain calcium. Expert After determining the calcium consumption rate, set up a continuous drip system. Use the following formula (or skip the math and use our Dosage Calculator) to determine how much to add to your top–off water: m=vc/160 (m=mL of product to add to top off water, v=volume of tank in liters, c=amount to raise calcium in mg/L). [For reference: 1 US gallon=3.8 L]. Notes If used with Reef Calcium, it is not necessary to exceed 380 mg/L total calcium. Use to measure calcium. DO NOT OVERDOSE: Excess calcium may enhance the loss of carbonate alkalinity. Do not directly mix with any carbonate supplement. Best if calcium & carbonate additives are added on alternate days or at least 30 minutes apart. Water Volume Units US Gallons Liters Current Ca mg/L (ppm) Desired Ca mg/L (ppm) To reach your desired level use mL ( caps) Do not exceed 12.5 mL/80 L (20 US gallons) Considerations Use Reef Status Calcium to test calcium levels. We recommend a Ca level between 380-420 mg/L with an alkalinity between 3-6 meq/L (8-17 dKH). It is advisable to make large adjustments slowly to avoid overshooting intended level or shocking corals and inverts. DO NOT OVERDOSE Do not exceed 12.5 mL/80 L (20 US gallons). Excess calcium may enhance the loss of carbonate alkalinity. Do not directly mix with any carbonate supplement. Best if calcium & carbonate additives are added on alternate days or at least 30 minutes apart. Box Contains water treatment
