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 3–6 meq/L (8–17 dKH). Alkalinity should not be allowed to fall below 2 meq/L.
Use 1 capful (5 mL) per 80 L (20 US 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.
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.
After determining the alkalinity 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=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].
Best to pour in gradually near strong water movement. Do not add to a sump or other area of slow water exchange.
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.
