Reef Carbonate™ is a concentrated (4,000 meq/L) optimized
blend of carbonate and bicarbonate salts designed to restore and
maintain alkalinity in the reef aquarium. 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 carbonates (Reef Carbonate™) and calcium (Reef advantage calcium or Reef Complete).
Whereas competing products simply use sodium bicarbonate,
Reef Carbonate™ is made with a blend of carbonate and bicarbonate salts.
This blend of salts results in Reef Carbonate™ yielding a pK of roughly
9.0 in saltwater (higher than competing products). In a closed reef
system, the multitude of organics produced by reef inhabitants tends to
force pH downward, but the advantage of Reef Carbonate’s™ higher pK is a
stabilization of pH around 8.3-8.4. Competing products’ formulations
make them incapable of such a claim, so pH will always fall below
desirable levels for a reef aquarium.
Used as directed, Reef Carbonate™ will not deplete calcium,
magnesium, or strontium which usually tend to precipitate with
increasing alkalinity. Reef alkalinity should be maintained at 3–5 meq/L
(8–14 dKH). Alkalinity should not be allowed to fall below 2 meq/L.
BEGINNER: Use 1 capful (5 mL) per 80 L (20 gallons) twice a
week. Best if diluted into a cup of freshwater, then added. Check
alkalinity every 2 weeks and adjust amount or frequency accordingly.
ADVANCED: Check alkalinity, then follow addition regimen
above until alkalinity is adjusted to 4–5 meq/L. Each mL contains a
minimum of 4 meq of alkalinity. Each 5 mL/80 L will raise alkalinity by
about 0.25 meq/L. Amount or frequency can be adjusted, but do not exceed
20 mL/80 L per day. Thereafter, use as required to maintain alkalinity.
EXPERT: After determining the alkalinity consumption rate,
set up a continuous drip system. Use the following formula to determine
how much to add to your top–off water: m=va/4 (m=mL of product to add to
top off water, v=volume of tank in liters, a=amount to raise alkalinity
in meq/L). For example, if you want to raise alkalinity by 1 meq/L in a
200 liter tank, then you would add (200x1)/4=50 mL into the top–off
water. [For reference: 1 gallon=3.8 L].
NOTES: Best to pour in gradually near strong water movement. Do not add to a sump or other area of slow water exchange. Use testing kit to measure total alkalinity or testing kit to measure carbonate alkalinity.
DO NOT OVERDOSE: Excess alkalinity may enhance the loss of
calcium, magnesium, and strontium. Do not directly mix with any calcium,
magnesium, or strontium supplement. Best if calcium & carbonate
additives are added on alternate days or at least 30 minutes apart.
