Seachem Reef Complete, 500 ml
Seachem 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
(such as 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.
BEGINNER: Use 1 capful per 20 gallons twice a week. Check calcium every two weeks.
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 top-off water: m=0.025vc (m=mL of product to add to top off water, v=volume of tank in gallons, c=amount to raise calcium in mg/L). For example, if you want to raise calcium by 20 mg/L in a 50 gallon tank, then you would add 0.025x50x20=25 mL into the top-off water.
