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 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.
Use 1 capful (5 mL) per 80 L (20 gallons*) twice a week. Check calcium every 2 weeks and adjust amount or frequency accordingly.
ADVANCED: Check calcium level, then follow dosing regimen above until calcium is adjusted to 380–420 mg/L. Each capful will raise calcium by about 10 mg/L. Size or frequency of amount added can be adjusted, but do not exceed 25 mg/L 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 to determine how much to add to your topâ€“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 gallon=3.8 L]. HINTS: If used with Reef Calcium™, it is not necessary to exceed 380 mg/L total calcium. Calcium over 400 mg/L is not recommended.
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.
