Seachem Reef Builder, 600 g

• Raises carbonate alkalinity (KH) with minimal impact on pH
• A blend of carbonate sources that will not lower pH
• Will not deplete calcium, magnesium, or strontium

Product Description Seachem Reef Builder 600G Directions Beginner Use 3 g (1/2 level teaspoon) per 150 L (40 US gallons) twice a week. Dissolve in at least 250 mL (1 cup) of freshwater. Check alkalinity every 2 weeks and adjust amount or frequency accordingly. For precise dosing, use the Seachem Digital Spoon Scale. Advanced Check alkalinity (use MultiTest Marine pH & Alkalinity to test alkalinity levels), then follow addition regimen above until alkalinity is adjusted to 3-6 meq/L (8-17 dKH). Each 3 g/150 L will raise alkalinity by about 0.25 meq/L. Quantity or frequency can be adjusted, but do not exceed 12 g/150 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 (or skip the math and use our Dosage Calculator) to determine how much to add to your top–off water: m=0.08va (m=grams 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 your alkalinity by 1 meq/L in a 200 liter tank, then you would add 0.08x200x1=16 g into the top–off water. [For reference: 1 gallon=3.8 liters, 6 g=1 teaspoon]. 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. Water Volume Units US Gallons Liters Current Alkalinity meq/L Desired Alkalinity meq/L To reach your desired level use g ( tspn) Do not exceed 12 g/150 L (40 US gallons) per day Considerations Use to test alkalinity levels. Reef alkalinity should ideally be maintained at 3-6 meq/L (8-17 dKH). Alkalinity should not be allowed to fall below 2 meq/L. It is advisable to make large adjustments slowly to avoid overshooting intended level or shocking corals and inverts. Dissolve in at least one cup of freshwater. DO NOT OVERDOSE Do not exceed 12 g/150 L (40 US gallons) per day. 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. Box Contains water treatment
