67.6 oz (4 x 16.9 oz) Seachem Reef Complete Raises Calcium and Maintains Magnesium and Strontium in Aquariums

Reef Complete is a concentrated (160,000 mg/L) optimized blend of ionic calcium designed to restore and maintain calcium to levels found in natural seawater without affecting pH. Calcium and carbonates are essential to all coral growth. If either becomes deficient, coral growth will cease, followed by a rapid decline in coral health. To prevent this you must provide calcium (Reef complete) and carbonates (Reef Builder or Reef Carbonate) Reef Complete also includes magnesium and strontium in amounts proportionate to typical utilization ratios (100:5:0.1, Ca:Mg: Sr). This allows one to maintain these two important elements while maintaining calcium. Reef Complete is a blended product. It is not simply calcium chloride. Commercially available calcium chloride contains ammonia. Unlike other ionic calcium supplements, Reef Complete is blended to a higher pH to force the ammonia to gas off into the atmosphere. Also, Reef Complete is more concentrated than any other liquid product on the market. Reef Complete contains 160,000 ppm calcium.

• Liquid Ionic Calcium Source
• Maintains Magnesium & Strontium
• Raises Calcium
• Essential to Coral Growth
• Will Not Affect pH

INSTRUCTIONS: Beginner: Use 1 capful (5 mL) per 80 L (20 US gallons) twice a week. Check calcium every 2 weeks and adjust the amount or frequency accordingly

Advanced: Check calcium level (use Reef Status: Calcium to measure calcium), then follow the 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 the tank in liters, c=amount to raise calcium in mg/L). [For reference: 1 US gallon=3.8 L].

If used with Reef Calcium, it is not necessary to exceed 380 mg/L total calcium. Use Reef Status: Calcium 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.
