| Reef Advantage Calcium
Reef Advantage Calcium™ is a non-caustic (pH 8.3–8.6) optimized
blend of ionic calcium designed to restore and maintain calcium
to levels found in natural seawater. 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.
Reef Advantage Calcium™ 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. Unlike limewater (kalkwasser), Reef Advantage Calcium™ does
not have a caustic pH and will not deplete magnesium. Used as directed,
it will not deplete alkalinity.
Directions
BEGINNER: Use 1 level teaspoon per 150 L (40 gallons*) twice a week.
Dissolve in at least one cup of freshwater. Check calcium every 2 weeks
and adjust dose or frequency accordingly. ADVANCED: Check calcium level,
then follow dosing regimen above until calcium is adjusted to 380–420
mg/L. Each dose will raise calcium by about 12 mg/L. Size or frequency
of dose 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: t=0.002vc (t=teaspoons
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 25 mg/L
in a 50 gallon* tank, then you would add 0.002x50x25=2.5 teaspoons into
the top-off water. HINTS: 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.
